explain what happens with light causing you to see colored opaque objects

Answers

answer:

an opaque object is one that doesn't let light pass through it. instead, it reflects or absorbs the light that strikes it.

explanation:

in this case, we see the material because of the transmitted light. therefore, the wavelength of the transmitted light determines the color that the object appears.

good luck :)

i hope this helps

have a nice day !!

I agree ^ that does happen when opaque objects are causing the light to see color

Answers

Answer:

sedimentary i think

Explanation:

Answer:

Rock A sedimentary

Rock B Metamorphic

Explanation:

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

The answer is A because there’s so much heat in the core and pressure because of all of the layers of the earth
Higher heat and pressure: higher heat results in more kinetic energy in particles, causing them to bounce of surfaces more equalling higher pressure

To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.

He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.

A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.

Explanation:

Black Final: 38

Black Change: 38 - 22 = 16

White Final: 24

White Change: 24 - 22 = 2

Green Final: 29

Green Change: 29 - 22 = 7
