Reflection, Refraction, and Absorption

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light when it hits a surface that it cannot pass through.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What is absorption in the context of light?

Back

Absorption is the process by which light is taken in by an object and converted to other forms of energy, such as heat.

Front

What happens to light when it passes from air to water?

Back

It refracts, or bends, due to a change in speed.

Front

What color does a leaf appear if it absorbs all colors except green?

Back

Green.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What happens to light when it hits a black object?

Back

A black object absorbs all colors of light and reflects none.

Front

What is the relationship between the medium and the speed of light?

Back

Light travels fastest in a vacuum and slowest in solids.

Front

What color appears when all colors of light are reflected?

Back

White.

Front

What is the effect of temperature on the speed of light?

Back

Temperature does not significantly affect the speed of light in a vacuum.
