Unit 6/7 Waves Test Review

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through. They cannot travel through a vacuum.

Front

What is a vacuum?

Back

A vacuum is a space that is completely empty of matter, including air.

Front

What is interference in the context of waves?

Back

Interference is the interaction between two or more waves that meet, resulting in a new wave pattern.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave.

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, such as light waves from the Sun.
