Front

Why does the lower part of a child appear different in size from the upper part when viewed through water?

Back

The light rays that travel through water and then into air are refracted.

Front

What is the angle of reflection equal to?

Back

The angle of incidence.

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

Define reflection in the context of light.

Back

Reflection is the bouncing back of light rays when they hit a surface.

Front

Define refraction in the context of light.

Back

Refraction is the bending of light rays as they pass from one medium to another.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What happens to light when it passes from a less dense medium to a more dense medium?

Back

It bends towards the normal.

Front

What happens to light when it passes from a more dense medium to a less dense medium?

Back

It bends away from the normal.
