Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is a non-mechanical wave?

Back

A non-mechanical wave does not require a medium to travel; an example is light.

Front

What is a transverse wave?

Back

In a transverse wave, the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

In a longitudinal wave, the particles of the medium move parallel to the direction of the wave's travel.
