Wave motion is characterized by two velocities: the velocity with which the wave moves in the medium (e. G. , air or a string) and the velocity of the medium (the air or the string itself). Consider a transverse wave traveling in a string. The mathematical form of the wave is.
a) The velocity of propagation of the wave V=w/k
b) The y velocity v_y(x,t) of a point on the string as a function of x
v=-wAcos(kx-wt)
What is a wave?
A wave can be described as a disturbance that travels through a medium from one location to another location
y(x,t)=Asin(kx−ωt) defines the wave equation.
a)The velocity of propagation of the wave
We are asked to find wave speed (v)
Recall that v = fλ
From the wave equation above,
k = 2π/ λ where k is the wave number and λ is the wavelength, λ = 2π /k
ω = 2πf where f is the frequency and ω is the angular frequency.
f = ω/ 2π.
By substituting for λ and ω into the wave speed formulae, we have that
v =( ω/ 2π) × (2π /k)
v = ω/k
b)The y velocity v_y(x,t) of a point on the string as a function of x
y(x,t)=Asin(kx−ωt)
The first derivative of y with respect to x give the velocity (vy)
By using chain rule, we have that

dentical rays of light in air are refracted upon entering three transparent materials: (a) water, where the speed of light is 0.75c ; (b) ethyl alcohol; speed 0.7c ; and (c) crown glass; speed 0.6c .
The transition from less dense air to denser glass or water causes light to slow down.
What happens to a ray of light as it passes through air and enters water?A beam of light (a collection of perpendicular rays) will move straight through the air when it is shone at it. Until they come into contact with an object, light rays typically go in straight paths.A sheet of glass's surface will reflect some light when a light ray strikes it, so this happens. However, because glass is transparent, a large portion of the light will flow through the glass.Light beams are similarly impacted by water. While some light will reflect off the water's surface, the translucent water will let in the majority of the light.The direction of a light ray changes when it travels through glass from the atmosphere. As it travels through the glass' surface, the light ray seems to bend.Similar effects occur when a light beam travels from air into water: the light ray is twisted as it collides with the water's surface.Refraction describes the "bending of a ray of light" when it travels through one substance and then another.When a light beam exits glass or water and enters the atmosphere, it will also bend.To Learn more About slow down refer to:

Two radio astronomers from the United States, Penzias and Wilson, recorded a signal in their radio telescope that was impossible to attribute to a specific source in the sky. Day or night, summer or winter, it appeared to have the same intensity everywhere. They came to the conclusion that the signal had to originate from outside of our galaxy. It almost came from the beginning of the universe.Their discovery was viewed by scientists as strong support for the "Big Bang" theory. According to this theory, the 'shockwave' of that primordial explosion would still be observable as a subdued 'wallpaper' coming from everywhere behind all galaxies, quasars, and galaxy clusters. As of right now, the Big Bang theory is still the only theory that can satisfactorily account for the CMB's existence.

In the photoelectric effect, a stopping potential of 3.2 V is needed for radiation of wavelength 200 nm.
(a)What is the work function (in eV) of the material?
(b) What is the maximum kinetic energy (in eV) of a photoelectron emitted from a surface whose work function is 5.0 eV when illuminated by a light whose wavelength is 200 nm?
(a) The work function is 7.5(10)¹⁴ Hz.
(b) The kinetic energy of photoelectron is - 1.898 eV
The photoelectric effect consists of the emission of electrons (electric current) that occurs when light falls on a metal surface under certain conditions.
If the light is a stream of photons and each of them has energy, this energy is able to pull an electron out of the crystalline lattice of the metal and communicate, in addition, a kinetic energy.
This is what Einstein proposed:
Light behaves like a stream of particles called photons with an energy
E = h.ν ----- eq1
So, the energy E of the incident photon must be equal to the sum of the Work function Φ of the metal and the kinetic energy K of the photoelectron:
E = Φ + K ----- eq2
Where Φ is the minimum amount of energy required to induce the photoemission of electrons from the surface of a metal, and its value depends on the surface.
In case, Φ = 5eV
So, applying equation (1) in this problem:
E = hν
Where:
h = 4.136(10)⁻¹⁵ eV is Planck constant
ν is the frequency
Now the frequency has an inverse relation with the wavelength
λ = 400(10)⁻⁹ m
ν = c/λ
Being c = 3(10)⁸ m/s is the speed of light in vacuum.
ν = 7.5(10)¹⁴ Hz.
Substituting,
E = 4.136(10)⁻¹⁵ {7.5(10)⁻¹⁰}
E = 3.1 eV
Now,
3.1 eV = 5 ev + K
K = - 1.898 eV
Since a negative kinetic energy is not physically possible, the only explanation is: the conditions for a photoelectric effect were not met, hence the photoelectric effect cannot occur.
Therefore, the main condition for the occurrence of the photoelectric effect is that the energy incident photon must be greater than the work function and E > Φ

What is speed?
An object's velocity (commonly denoted by v) is the rate of change of position over time, or the rate of change of position per unit time. So it's a scalar quantity. The average velocity of an object over a time interval is the distance traveled by the object divided by the duration of the interval. The instantaneous velocity is the limit of the average velocity as the time interval approaches zero. Velocity is not the same as speed.
Velocity is the dimension of distance divided by time. The SI unit for speed is meters per second (m/s), but the most common everyday speed units are kilometers per hour (km/h) or miles per hour (mph) in the US and UK. ). Knots are widely used in air and sea travel.
According to special relativity, the fastest speed at which energy or information can travel is the speed of light in a vacuum c = 299792458 meters/second (approximately 10790000000 km/h or 671000000 mph).

Voltage is proportional to inductance just as, for resistors, it is proportional to resistance. Now, the (independent) voltages for parallel elements are equal (V₁ = V₂) and the currents (which are generally functions of time) add i(t) = i₁(t) + i₂(t)
This leads to the equation,
i = i₁ + i₂ + i₃ = V [(1/R₁) + (1/R₂) + (1/R₃)] for resistors.
We note that this condition on the currents implies
d₁(t)/dt + d₂(t)/dt = d(it)/dt
Thus, although the inductance equation, ε = -L(di/dt) involves the rate of change of current, as opposed to current itself, the conditions that led to the parallel resistor formula also apply to inductors.

The lens should be kept at a distance of 3.67 cm from the film in the camera to be photographed and convex lens should be used.
Focal length = f = 35.0 mm = 3.5 cm
Distance at which flower is kept = p = 75 cm
The type of lens that should be used = convex
Distance at which camera should be kept = q =
= Using the lens formula
= 1/p + 1/q = 1/f
= 1/75 + 1/q = 1/3.5
= 1/q = 1/3.5 - 1/75
= q = 3.67 cm
So, the film should be kept 3.67 cm behind the convex lens.

in electronic circuits, when analyzing the effect of l or c on the wave shape of non sinusoidal voltages, what is useful?
It retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude.
What has a sinusoidal wave form?Periodic waveforms known as sine waves can be represented graphically using the sine or cosine trigonometric functions. Electrical circuits that receive "AC" voltages and currents, or sinusoidal waveforms whose polarity alternates on each cycle.The strength of the magnetic field that forms around a wire or conductor while an electric current flows through it is inversely proportional to the current value. The movement of this single wire conductor through the magnetic flux induces a "EMF" (Electromotive Force) inside the conductor if it is moved or rotated within a stationary magnetic field.It retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property. This property leads to its importance in Fourier analysis and makes it acoustically unique.To learn more about sinusoidal wave, refer to

Expansion of the universe after its origin takes place by a phenomenon called inflation.
What is inflation?In physical cosmology, a theory of exponential expansion of space in the early universe is called inflation.Prior to the Big Bang, the universe underwent a breathtaking cosmic expansion, doubling in size in a fraction of a second. This rapid inflation, fueled by energy that permeated empty space and left the universe desolate and cold.The Big Bang theory explains how the universe got from the hot dense state of the early universe to the cold dense state whereas cosmic inflation is an explanation of some properties of the cosmic microwave background radiation.Phenomena can be defined as “observable events that occur in a natural or designed system.” They are everywhere around us, but some are easier to notice than others. Common examples of natural phenomena include lightning, earthquakes, tsunamis, volcanic eruptions, tornadoes, and similar.The natural phenomena in the given crossword are cyclone, thunder, storm, lightning, typhoon and hurricane.To learn more about phenomenon refer to:

what frequency of rotation, in rpm , is required to give an acceleration of 1.4 g to an astronaut's feet, if her feet are 1.1 m from the platform's rotational axis?
The frequency of the rotation having a radius of 1.1 m is 3.53 rpm
The rotational acceleration = 1.4 g
The radius of the rotation = 1.1 m
The frequency of the rotation can be found using the formula,
ω = √(α/r)
where ω is the frequency of the rotation
α is the acceleration of the rotation
r is the radius of the rotation
Let us substitute the known values in the above equation, we get
ω = √ (1.4 x 9.8 / 1.1 )
= √ (13.72 / 1.1)
= √12.47
ω = 3.53
Therefore the frequency of the rotation is 3.53 rpm
