Reflection, refraction, diffraction

Front

What is diffraction?

Back

The spreading out of waves as they pass through an opening or around objects.

Front

What is refraction?

Back

The bending of a wave disturbance as it passes from one medium into another.

Front

What happens to a light ray when it strikes a mirror?

Back

According to the Law of reflection, it bounces off the mirror at the same angle it hits.

Front

Why does a pencil appear broken when placed in a cup of water?

Back

Because light bends when it passes through water.

Front

What is the definition of reflection?

Back

The bouncing back of light waves when they hit a surface.

Front

What is the Law of Reflection?

Back

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

Front

What is a medium in the context of waves?

Back

A substance through which a wave can travel, such as air, water, or glass.

Front

What is an example of diffraction?

Back

The spreading of sound waves as they pass through a doorway.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of waves, while refraction is the bending of waves as they pass into a different medium.

Front

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

Back

It bends, causing objects to appear displaced.
