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 reflection in the context of waves?

Back

The bouncing back of waves when they hit a surface.

Front

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

Back

Light bends when it passes through water.

Front

What is refraction?

Back

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

Front

What is an example of reflection?

Back

Light waves bouncing off the surface of a lake.

Front

What is the role of sonar in detecting objects?

Back

Sonar uses reflection of sound waves to detect objects underwater.

Front

What is the definition of a medium in wave physics?

Back

A medium is a substance through which a wave can travel.

Front

How does light behave when it travels from one medium to another?

Back

Light bends at the boundary between different media.

Front

What is an example of diffraction?

Back

The spreading of sound waves as they pass through a narrow opening.

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 enter a different medium.
