What is amplitude?

Back

A measure of wave energy, defined as the distance from the wave's resting position to the crest or trough.

Front

What do waves transfer?

Back

Energy, which is the ability to do work.

Front

What is compression in a longitudinal wave?

Back

The part where the particles are close together.

Front

What is wavelength?

Back

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

Front

What is frequency?

The number of waves that pass a point in one second.

Front

What is rarefaction in a longitudinal wave?

Back

The part where the particles are spread apart.

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What is sound?

Back

A type of wave that travels through a medium, such as air, and is detected by our ears.
