Front

What happens to a light ray when it strikes an object?

Back

It is reflected.

Front

What can be concluded if a beam of light bends more when passing from water into glass than from air into water?

Back

Glass is denser than water.

Front

What is the law of reflection?

Back

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

Front

What is refraction?

Back

The bending of light as it passes from one medium to another.

Front

What is the medium in the context of waves?

Back

The substance through which a wave travels.

Front

What is total internal reflection?

Back

The complete reflection of a light ray back into a medium when it hits the boundary at an angle greater than the critical angle.

Front

What is the critical angle?

Back

The angle of incidence above which total internal reflection occurs.
