Light: Travel, Reflection, and Refraction

Front

What happens to most of the light that strikes a black object?

Back

It is absorbed.

Front

What happens to the speed of light when it passes from air into water?

Back

It slows down.

Front

How does light travel through a vacuum?

Back

Reflection is when light hits an object and bounces off.

Front

What happens to light when it is reflected off a mirror?

Back

The light is being reflected off the mirror.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is transmission in the context of light?

Back

Transmission is when light passes through an object without being absorbed or reflected.

Front

What is the difference between reflection and refraction?

Back

Reflection is bouncing off a surface, while refraction is bending as it passes through a medium.

Front

What is a medium in terms of light travel?

Back

A medium is a substance through which light travels, such as air, water, or glass.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.
