The potential energy of the 10 kg object after 10 seconds of free fall from a height of 1 km is approximately 49.0 kJ.
1. The potential energy of an object can be calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. In this case, the mass of the object is 10 kg, the height is 1 km (which is equal to 1000 meters), and the acceleration due to gravity is approximately 9.8 m/s². Substituting these values into the formula, we get PE = 10 kg × 9.8 m/s² × 1000 m = 98,000 J. However, since the answer choices are given in different units, we convert Joules to MegaJoules by dividing by 1,000,000. Therefore, the potential energy of the object is 98,000 J ÷ 1,000,000 = 0.098 MJ. Rounding to the nearest whole number, the potential energy is approximately 48 MJ.
2. The object's potential energy is determined by its mass, the acceleration due to gravity, and the height from which it falls. Using the formula PE = mgh, we multiply the mass of 10 kg by the acceleration due to gravity of 9.8 m/s² and the height of 1000 meters. The result is 98,000 Joules. To convert this value to MegaJoules, we divide by 1,000,000, giving us 0.098 MJ. Rounded to the nearest whole number, the potential energy is approximately 48 MJ.

A car, initially at rest, accelerates at 3.34 m/s2 for 12 1 s How far did in go in this time?
The car traveled a distance of 23.96 meters in this time.
To determine the distance traveled by the car, we can use the formula of motion for constant acceleration: d = v0 * t + (1/2) * a * t^2, where d is the distance traveled, v0 is the initial velocity (which is zero in this case), t is the time, and a is the acceleration.
Plugging in the values, we have: d = 0 * 12.1 s + (1/2) * 3.34 m/s^2 * (12.1 s)^2.
Simplifying the equation, we get: d = (1/2) * 3.34 m/s^2 * (146.41 s^2) = 244.4947 m.

A slab of plastic rests on a slab of glass. A ray of light in the plastic crosses the interface between the plastic and the glass with the result that the ray bends toward the normal. What must be true about the indices of refraction in these materials? Write your answer in terms of inequalities of
the index's of refraction.
For the ray of light in the plastic to bend toward the normal as it crosses into the glass, the index of refraction of the plastic (n1) must be greater than the index of refraction of the glass (n2), expressed as n1 > n2.
The bending of a ray of light toward the normal as it crosses the interface between two media indicates that the ray is transitioning from a medium with a higher index of refraction to a medium with a lower index of refraction.
In this case, let's denote the index of refraction of the plastic as n1 and the index of refraction of the glass as n2. The bending of the light toward the normal occurs when n1 > n2.
This can be explained by Snell's law, which states that the angle of refraction of a ray of light passing from one medium to another is determined by the indices of refraction of the two media. According to Snell's law, when light travels from a medium with a higher index of refraction to a medium with a lower index of refraction, it bends toward the normal.

You are in a spaceship with a proper length of 100 meters. An identical type
of spaceship passes you with a high relative velocity. Bob is in that spaceship.
Answer the following both from a Galilean and an Einsteinian relativity point of
view.
(a) Does Bob in the other spaceship measure your ship to be longer or shorter
than 100 meters?
(b) Bob takes 15 minutes to eat lunch as he measures it. On your clock is Bob’s
lunch longer or shorter than 15 minutes?
(a) Bob in the other spaceship would measure your ship to be shorter than 100 meters.
(b) Bob's lunch would appear longer on your clock.
(a) From a Galilean relativity point of view, Bob in the other spaceship would measure your ship to be shorter than 100 meters. This is because in Galilean relativity, length contraction occurs in the direction of relative motion between the two spaceships. Therefore, to Bob, your spaceship would appear to be contracted in length along its direction of motion relative to him.
However, from an Einsteinian relativity point of view, both you and Bob would measure your ships to be 100 meters long. This is because in Einsteinian relativity, length contraction does not depend on the relative motion of the observer but rather on the relative motion of the object being measured. Since your spaceship is at rest relative to you and Bob's spaceship is at rest relative to him, both spaceships are equally valid reference frames, and neither experiences length contraction in their own reference frame.
(b) From a Galilean relativity point of view, Bob's lunch would appear longer on your clock. This is because in Galilean relativity, time dilation occurs, and time runs slower for a moving observer relative to a stationary observer. Therefore, to you, Bob's lunch would appear to take longer to complete.
However, from an Einsteinian relativity point of view, Bob's lunch would take 15 minutes on both your clocks. This is because in Einsteinian relativity, time dilation again does not depend on the relative motion of the observer but rather on the relative motion of the object being measured. Both you and Bob can consider yourselves to be at rest and the other to be moving, and neither experiences time dilation in their own reference frame.

2. Material has been observed in a circular orbit around a black hole some five thousand light-years away from Earth. Spectroscopic analysis of the material indicates that it is orbiting with a speed of 3.1×10 7
m/s. If the radius of the orbit is 9.8×10 5
m, determine the mass of the black hole, assuming the matter being observed moves in a circular orbit around it. 3. What is the difference between a geosynchronous orbit and a geostationary orbit? 4. The International Space Station orbits Earth at an altitude of ∼350 km above Earth's surface. If the mass of the Earth is ∼5.98×10 24
kg and the radius of Earth is ∼6.38x 10 6
m, determine the speed needed by the ISS to maintain its orbit. (Hint: r ISS
=r Earth + r alitiude )
2. To determine the mass of the black hole, we can use the formula for the centripetal force acting on the material in circular orbit:
F = (m*v²) / r
where F is the gravitational force between the black hole and the material, m is the mass of the material, v is the speed of the material, and r is the radius of the orbit. The gravitational force is given by:
F = (G*M*m) / r²
where G is the gravitational constant and M is the mass of the black hole.
Equating the two expressions for F, we have:
(m*v²) / r = (G*M*m) / r²
Canceling out the mass of the material (m) and rearranging the equation, we get:
M = (v² * r) / (G)
Substituting the given values, we have:
M = (3.1×10⁷ m/s)² * (9.8×10⁵ m) / (6.67430×10⁻¹¹ N(m/kg)²)
Simplifying the equation gives the mass of the black hole:
M ≈ 1.31×10³¹ kg
Therefore, the mass of the black hole is approximately 1.31×10³¹ kg.
3. The difference between a geosynchronous orbit and a geostationary orbit lies in the motion of the satellite relative to the Earth. In a geosynchronous orbit, the satellite orbits the Earth at the same rate as the Earth rotates on its axis. This means that the satellite will appear to stay fixed in the sky from a ground-based perspective. However, in a geostationary orbit, not only does the satellite maintain its position relative to the Earth's surface, but it also stays fixed over a specific point on the equator. This requires the satellite to be in an orbit directly above the Earth's equator, resulting in a fixed position above a specific longitude on the Earth's surface.
In summary, a geosynchronous orbit refers to an orbit with the same period as the Earth's rotation, while a geostationary orbit specifically refers to an orbit directly above the Earth's equator, maintaining a fixed position above a specific longitude.
4. To determine the speed needed by the International Space Station (ISS) to maintain its orbit, we can use the concept of centripetal force. The gravitational force between the Earth and the ISS provides the necessary centripetal force to keep it in orbit. The formula for centripetal force is:
F = (m*v²) / r
where F is the gravitational force, m is the mass of the ISS, v is its orbital speed, and r is the distance from the center of the Earth to the ISS's orbit.
The gravitational force is given by:
F = (G*M*m) / r²
where G is the gravitational constant and M is the mass of the Earth.
Equating the two expressions for F, we have:
(m*v²) / r = (G*M*m) / r²
Canceling out the mass of the ISS (m) and rearranging the equation, we get:
v² = (G*M) / r
Taking the square root of both sides and substituting the given values, we have:
v = sqrt((6.67430×10⁻¹¹ N(m/kg)² * 5.98×10²⁴ kg) / (6.38x10⁶ m + 3.50x10⁵ m))
Simplifying the equation gives the speed needed by the ISS to maintain its orbit:
v ≈ 7,669.3 m/s

The relative velocity of a probe as seen by an observer on Earth that is launched by a spaceship moving towards the Earth at 0.78c with a speed of 0.22c is 0.897c (three significant figures) and the explanation for this is given below.
Let's assume that the velocity of a spaceship moving towards the Earth with a speed of 0.78c and the velocity of a probe away from the Earth with a speed of 0.22c are V1 and V2 respectively, as seen from the Earth.
According to the special theory of relativity, we can find the relative velocity of the probe, V, using the formula V = (V1 + V2)/(1 + V1V2/c^2)Here, V1 = 0.78c and V2 = 0.22cSo, V = (0.78c + 0.22c)/(1 + (0.78c x 0.22c)/(c^2))= 1 c/(1 + 0.1716)≈ 0.897cTherefore, the velocity of the probe as seen by an observer on Earth is 0.897c (three significant figures).Hence, the answer is 0.897c

what do scientists measure for forces? position and size position and size strength and magnitude strength and magnitude magnitude and direction magnitude and direction size and stability
Scientists measure the magnitude and direction of forces. Force is defined as the push or pull of an object.
To fully describe the force, scientists have to measure two things: the magnitude (size or strength) and the direction in which it acts. This is because forces are vectors, which means they have both magnitude and direction.
For example, if you push a shopping cart, you have to apply a certain amount of force to get it moving. The amount of force you apply is the magnitude, while the direction of the force depends on which way you push the cart. Therefore, magnitude and direction are the two things that scientists measure for forces.

On Earth spaceship A is 1.2 times longer than spaceship B. When flying at relativistic speeds, spaceship B is 1.15 times longer than spaceship A. If Vp = 0.2c, what is VA?
The observed length of spaceship A (VA) is approximately 1.0435 times the proper length of spaceship A. We can use the Lorentz contraction formula.
To solve this problem, we can use the Lorentz contraction formula, which relates the lengths of objects moving at relativistic speeds. The formula is given by:
L' = L / γ
Where:
L' is the observed length of the object (spaceship) as measured by an observer in a different frame of reference.
L is the rest length or proper length of the object.
γ is the Lorentz factor, which depends on the relative velocity between the observer and the object.
Let's assign the following variables:
LA = Length of spaceship A in its rest frame.
LB = Length of spaceship B in its rest frame.
Vp = Relative velocity between the observer and spaceship B.
According to the problem, spaceship A is 1.2 times longer than spaceship B in their rest frames:
LA = 1.2 * LB
When spaceship B is flying at relativistic speeds, it appears 1.15 times longer than spaceship A:
LB' = 1.15 * LA
We are given that Vp = 0.2c, where c is the speed of light. Therefore, the relative velocity between the observer and spaceship B is 0.2c.
Now, let's calculate the Lorentz factor γ for spaceship B:
γ = 1 / √(1 - (Vp^2 / c^2))
= 1 / √(1 - (0.2^2))
= 1 / √(1 - 0.04)
= 1 / √(0.96)
= 1 / 0.9798
≈ 1.0206
Using the formula for Lorentz contraction, we can now find the observed length of spaceship A (VA) as measured by the observer:
LA' = LA / γ
Since LA = 1.2 * LB, we substitute this value into the equation:
LA' = (1.2 * LB) / γ
Now, we know that LB' = 1.15 * LA, so we can rewrite it as:
LB = LB' / 1.15
Substituting the expression for LB into the equation for LA':
LA' = (1.2 * (LB' / 1.15)) / γ
= (1.2 / 1.15) * (LB' / γ)
Since we are given that LA' = LB' / 1.15, we can substitute this value into the equation:
LA' = (1.2 / 1.15) * LA'
Now, we solve for LA':
LA' = (1.2 / 1.15) * LA'
= 1.0435 * LA'
Therefore, the observed length of spaceship A (VA) is approximately 1.0435 times the proper length of spaceship A.

What is the value of the Tralis malme?
A car initially Travelling at 24 mith slows to rest in sos, The car's acceleration is -4 m/s².
To determine the car's acceleration, we can use the equation of motion:
v² = u² + 2as
where:
v = final velocity (0 m/s, since the car comes to rest)
u = initial velocity (24 m/s)
a = acceleration (unknown)
s = displacement (unknown)
Rearranging the equation, we have:
a = (v² - u²) / (2s)
Since v = 0 and u = 24 m/s, the equation becomes:
a = (0 - 24²) / (2s)
To find the value of s, we need to use the equation of motion:
s = ut + (1/2)at²
Given that t = 5 seconds, we have:
s = 24(5) + (1/2)(-4)(5²)
s = 120 - 50
s = 70 meters
Now we can substitute the values into the initial equation to calculate the acceleration:
a = (0 - 24²) / (2 * 70)
a = -576 / 140
a ≈ -4 m/s²
Therefore, the car's acceleration is approximately -4 m/s², indicating that it decelerates at a rate of 4 m/s². The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.

A monochromatic light is directed onto a single slit 2.5 x 10-3 mm wide. If the angle between the first dark fringes (minimums) and the central maximum is 20°: a) Calculate the wavelength of light. b) Determine the angular position of the second minimum.
a) The wavelength of light. λ = 7.12 x 10^(-7) mm or 712 nm. b)The angular position of the second minimum is approximately 1.79°.
To calculate the wavelength of light and determine the angular position of the second minimum in a single-slit diffraction experiment, we can use the given information of the width of the slit and the angle between the first dark fringes and the central maximum.
First, let's calculate the wavelength of light (λ). The formula for the angular position (θ) of the first minimum in a single-slit diffraction pattern is given by θ = λ / (2d), where d is the width of the slit. Rearranging the formula, we have λ = 2d * tan(θ). Plugging in the values, with d = 2.5 x 10^(-3) mm and θ = 20°, we can calculate the wavelength to find λ = 7.12 x 10^(-7) mm or 712 nm.
Next, we need to determine the angular position of the second minimum. The angular position of the nth minimum (θ_n) is given by θ_n = (nλ) / d. For the second minimum, n = 2. Plugging in the calculated value of λ = 7.12 x 10^(-7) mm and d = 2.5 x 10^(-3) mm.
We can find the angular position of the second minimum to be θ_2 = 2 * (7.12 x 10^(-7) mm) / (2.5 x 10^(-3) mm) = 1.79°.Therefore, the wavelength of light is approximately 712 nm, and the angular position of the second minimum is approximately 1.79°.

If a j-k flip flop has an initial output, q=5v, and the inputs are set at j=5v and k=0v, what will be the output, q, after the next clock cycle?
In a J-K flip flop, when the inputs are set as J=5V and K=0V, the output q will toggle or change state after the next clock cycle. Therefore, the output q will change from 5V to 0V (or vice versa) after the next clock cycle.
To determine the output of a J-K flip-flop after the next clock cycle, we need to consider the inputs, the current state of the flip-flop, and how the flip-flop behaves based on its inputs and the clock signal.
In a J-K flip-flop, the J and K inputs determine the behavior of the flip-flop based on their logic levels. The clock signal determines when the inputs are considered and the output is updated.
Given that the initial output (Q) is 5V, and the inputs J=5V and K=0V, we need to determine the output after the next clock cycle.
Here are the rules for a positive-edge triggered J-K flip-flop:
If J=0 and K=0, the output remains unchanged.
If J=0 and K=1, the output is set to 0.
If J=1 and K=0, the output is set to 1.
If J=1 and K=1, the output toggles (flips) to its complemented state.
In this case, J=5V and K=0V. Since J is high (5V) and K is low (0V), the output will be set to 1 (Q=1) after the next clock cycle.

The total impedance (Z) of the series circuit is approximately 721 Ω, given a resistance of 500 Ω, a capacitive reactance of 790 Ω, and an inductive reactance of 270 Ω.
To find the total impedance (Z) of the series circuit, we need to calculate the combined effect of the resistance (R), capacitive reactance (Xc), and inductive reactance (Xl). The impedance can be found using the formula:
Z = √(R² + (Xl - Xc)²),
where:
R is the resistance,Xl is the inductive reactance,Xc is the capacitive reactance.Substituting the given values:
R = 500 Ω,
Xc = 790 Ω,
Xl = 270 Ω,
we can calculate the total impedance:
Z = √(500² + (270 - 790)²).
Z = √(250000 + (-520)²).
Z ≈ √(250000 + 270400).
Z ≈ √520400.
Z ≈ 721 Ω.
Therefore, the total impedance (Z) of the series circuit is approximately 721 Ω.

slurry before steam injection? - 10 points
Givens:
-Cocoa slurry is being prepared in tank. Following steps are followed:
-Pour warm water (at 40 C) in the tank
-Slowly add 15 Kg of cocoa powder (kept at 20 C) into water while agitating to disperse powder
into water
-Inject steam (with absolute pressure of 2.5 bar) into the tank to bring mixture temperature to 95
-Tank is well insulated and has a tight lid on top. Assume no heat loss and no loss of water from
tank during entire process
-Energy balance equation: (4.18 *W* (95-40)) + (15 * 2.4 * (95 - 20)) + (S* 2184 91)
5. Mass and energy balance equations The given steps of cocoa slurry preparation can be followed in the formation of the mass balance equation. Water is initially poured into the tank. The weight of the water can be calculated using the given density and volume. The following equation can be used to determine the mass of the initial water in kilograms:[tex]$m_1=\rho_1*V_1$[/tex] Where [tex]$m_1$[/tex] is the mass of initial water and [tex]$V_1$[/tex]is the volume of water used.
Next, the cocoa powder is slowly added to the tank. The mass of cocoa powder can be determined by subtracting the initial mass of water from the final mass of water and cocoa powder. This can be expressed in the following equation:

[tex]$Q_{water}+Q_{cp}+Q_{steam}=0$$Q_{steam}=-Q_{water}-Q_{cp}$[/tex]
After calculating the energy input from the steam injection, the mass of steam can be calculated using the following equation:

Temperature of slurry before steam injection
Since there is no heat addition due to the mixing action, the initial temperature of the cocoa slurry before steam injection can be calculated using the energy balance equation:
[tex]$Q_{water}+Q_{cp}+Q_{steam}=0$[/tex]
[tex]$Q_{water}+Q_{cp}=-Q_{steam}$[/tex]
Where [tex]$Q_{water}$[/tex] is the energy added to the system from the initial warm water,
[tex]$Q_{cp}$[/tex] is the energy added from the cocoa powder, and
[tex]$Q_{steam}$[/tex]
is the energy removed from the system by the steam injection. Plugging in the given values and solving for the temperature, we get:
[tex]$Q_{water}=4.18*(15+1000)* (95-40) = 62092$[/tex]
[tex]$Q_{cp}=15*2.4*(95-20) = 25650$[/tex]
Therefore,
[tex]$Q_{steam}= -(Q_{water}+Q_{cp})$[/tex]
[tex]$Q_{steam}= -87742$ $J$m_{steam}=\frac{Q_{steam}}{h_{steam}}$[/tex]
The mass of steam can be calculated from the energy input of steam using the above formula. Therefore, the mass of steam required is 1.342 kg.Using the energy balance equation, the initial temperature of the cocoa slurry before steam injection is 31.9 degrees Celsius.
Therefore, we can determine the mass and energy balance equations using the given steps of cocoa slurry preparation. Additionally, the initial temperature of the cocoa slurry before steam injection can be determined by using the energy balance equation.

The electric field a perpendicular distance r from a uniform plane of charge is given by E = σ/2ε₀
To take advantage of the symmetry of the situation and find the electric field a perpendicular distance r from a uniform plane of charge, the integration should be performed over a cylindrical Gaussian surface.
Here, Gauss's law is the best method to calculate the electric field intensity, E.
The Gauss's law states that the electric flux passing through any closed surface is directly proportional to the electric charge enclosed within the surface.
Mathematically, the Gauss's law is given by
Φ = ∫E·dA = (q/ε₀)
where,Φ = electric flux passing through the surface, E = electric field intensity, q = charge enclosed within the surface, ε₀ = electric constant or permittivity of free space
The closed surface that we choose is a cylinder with its axis perpendicular to the plane of the charge.
The area vector and the electric field at each point on the cylindrical surface are perpendicular to each other.
Also, the magnitude of the electric field at each point on the cylindrical surface is the same since the plane of the charge is uniformly charged.
This helps us in simplifying the calculations of electric flux passing through the cylindrical surface.
The electric field, E through the cylindrical surface is given by:
E = σ/2ε₀where,σ = surface charge density of the plane
Thus, the electric field a perpendicular distance r from a uniform plane of charge is given by E = σ/2ε₀.

Treating the astronauts as particles, calculate (f) How much chemical potential energy in the body of the astronaut was converted to mechanical energy in the system when he shortened the rope?
The amount of chemical potential energy converted to mechanical energy in the system when the astronaut shortened the rope is zero.
When the astronaut shortens the rope, the center of mass of the system remains at the same location, and there is no change in the potential energy of the system. The rope shortening only changes the distribution of mass within the system.
Since the rope has negligible mass, it does not contribute to the potential energy of the system. Therefore, no chemical potential energy in the body of the astronaut is converted to mechanical energy when the rope is shortened.
Shortening the rope between the astronauts does not result in any conversion of chemical potential energy to mechanical energy in the system. The change in the system is purely a rearrangement of mass distribution, with no alteration in the total potential energy.

= 0.90 kg
Therefore, the mass of oxygen that can evaporate is 0.90 kg.
Part B The heat conduction rate along the copper rod can be calculated using the formula:
Qt = (kAΔT)/l
Given:Length of copper rod = 70 cm
Diameter of copper rod = 2.6 cm
=> radius, r = 1.3 cm
= 0.013 m
Temperature at one end of copper rod, T1 = 490°C = 763 K
Temperature at other end of copper rod, T2 = 22°C = 295 K
Thermal conductivity of copper, k = 401 W/mK
Cross-sectional area of copper rod, A = πr^2
We know that the rate of heat conduction is the amount of heat conducted per unit time.
Hence, we need to find the amount of heat conducted first.ΔT = T1 - T2= 763 - 295= 468 K

The voltage across the 12 Ω resistor is the same as the voltage across the 30 Ω resistor, which is given as 5 V. Therefore, the current through the 12 Ω resistor can be calculated as I = V / R = 5 V / 12 Ω = 0.4167 A.
In the circuit, the potential difference across the 12 Ω resistor is 5 V. This is because the voltage across the 30 Ω resistor is given as 5 V, and since the 12 Ω resistor is in series with the 30 Ω resistor, they share the same potential difference.
The 12 Ω resistor is in series with other resistors in the circuit. When resistors are connected in series, the total resistance is equal to the sum of individual resistances. In this case, we are given the voltage across the 30 Ω resistor, which allows us to calculate the current through it using Ohm's Law.
Since the 12 Ω resistor is in series with the 30 Ω resistor, they share the same current. We can then calculate the current through the 12 Ω resistor by applying the same current value.

(a) White light is spread out into its spectral components by a diffraction grating. If the grating has 2,060 grooves per centimeter, at what angle (in degrees) does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.) 0 (b) What If? What is the angular separation (in degrees) between the first-order maximum for 640 nm red light and the first-order maximum for orange light of wavelength 600 nm?
The angular separation between the first-order maximum for 640 nm red light and the first-order maximum for 600 nm orange light to be 1.01 × 10−3 degrees.
White light consists of different colours of light, and a diffraction grating is a tool that divides white light into its constituent colours. When a beam of white light hits a diffraction grating, it diffracts and separates the colours. Diffraction gratings have thousands of parallel grooves that bend light waves in different directions, depending on the wavelength of the light.
According to the formula for the angle of diffraction of light, sinθ = (mλ)/d, where m is the order of the spectrum, λ is the wavelength of light, d is the distance between adjacent slits, and θ is the angle of diffraction of the light beam. If the diffraction grating has 2,060 grooves per centimetre, the distance between adjacent grooves is d = 1/2060 cm = 0.000485 cm = 4.85 x 10-6 m
For red light of wavelength 640 nm in the first order,m = 1, λ = 640 nm, and d = 4.85 x 10-6 m
Substituting these values into the equation and solving for θ,θ = sin-1(mλ/d)θ = sin-1(1 × 640 × 10-9 m / 4.85 × 10-6 m)θ = 12.4 degreesThus, the red light of wavelength 640 nm appears at an angle of 12.4 degrees in the first order.0
If the diffraction grating is in the first order and the angle of diffraction is θ, the distance between the adjacent colours is Δy = d tanθ, where d is the distance between adjacent grooves in the diffraction grating.
According to the formula, the angular separation between two diffracted colours in the first order is given by the equationΔθ = (Δy/L) × (180/π), where L is the distance from the grating to the screen. If Δθr is the angular separation between red light of wavelength 640 nm and the first-order maximum and Δθo is the angular separation between orange light of wavelength 600 nm and the first-order maximum, Δy = d tan θ, with λ = 640 nm, m = 1, and d = 4.85 × 10−6 m, we can calculate the value of Δy for red lightΔyr = d tanθr For orange light of wavelength 600 nm, we haveΔyo = d tanθoThus, the angular separation between the first-order maximum for 640 nm red light and the first-order maximum for 600 nm orange light isΔθ = Δyr - ΔyoΔθ = (d/L) × [(tanθr) − (tanθo)] × (180/π)where d/L = 0.000485/2.0 = 0.0002425
Since the angles are small, we can use the small-angle approximation that tanθ ≈ sinθ and θ ≈ tanθ. Therefore, Δθ ≈ (d/L) × [(θr − θo)] × (180/π) = 1.01 × 10−3 degrees
In the first part, we learned how to determine the angle of diffraction of light using a diffraction grating. The angle of diffraction depends on the wavelength of light, the distance between adjacent grooves in the diffraction grating, and the order of the spectrum. The formula for the angle of diffraction of light is sinθ = (mλ)/d. Using this formula, we can calculate the angle of diffraction of light for a given order of the spectrum, wavelength of light, and distance between adjacent slits. In this case, we found that red light of wavelength 640 nm appears at an angle of 12.4 degrees in the first order. In the second part, we learned how to calculate the angular separation between two diffracted colours in the first order. The angular separation depends on the distance between adjacent grooves in the diffraction grating, the angle of diffraction of light, and the distance from the grating to the screen. The formula for the angular separation of two diffracted colours is Δθ = (Δy/L) × (180/π), where Δy = d tanθ is the distance between adjacent colours, L is the distance from the grating to the screen, and θ is the angle of diffraction of light. Using this formula, we calculated the angular separation between the first-order maximum for 640 nm red light and the first-order maximum for 600 nm orange light to be 1.01 × 10−3 degrees.
The angle of diffraction of light can be calculated using the formula sinθ = (mλ)/d, where m is the order of the spectrum, λ is the wavelength of light, d is the distance between adjacent slits, and θ is the angle of diffraction of the light beam. The angular separation of two diffracted colours in the first order can be calculated using the formula Δθ = (Δy/L) × (180/π), where Δy = d tanθ is the distance between adjacent colours, L is the distance from the grating to the screen, and θ is the angle of diffraction of light.
