Parts of a wave

Front

What is a wave crest?

Back

The highest point of a wave.

Front

What is a wave trough?

Back

The lowest point of a wave.

Front

What is amplitude in a wave?

Back

The maximum distance that the particles of a wave move from their rest position.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is compression in a wave?

Back

The part of a wave where the particles are close together.

Front

What is rarefaction in a wave?

Back

The part of a wave where the particles are spread out.

Front

How does increasing amplitude affect sound?

Back

The sound gets louder.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases.

Front

What is a transverse wave?

Back

A wave in which the particles move perpendicular to the direction of the wave.

Front

What is a longitudinal wave?

Back

A wave in which the particles move parallel to the direction of the wave.
