Front

What is the definition of a mechanical wave?

Back

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

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel, while longitudinal waves have oscillations parallel to the direction of wave travel.

Front

What is amplitude in the context of waves?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is wavelength?

Back

The distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is frequency?

Back

The number of waves that pass a given point in one second, measured in Hertz (Hz).
