Properties of Waves

Front

The lowest point of a wave

Back

Trough

Front

The highest point of a wave

Back

Crest

Front

The number of waves in a given time

Back

Frequency

Front

The time it takes for one wavelength to pass a point

Back

Period

Front

The distance from the crest of one wave to the crest of the next wave

Back

Wavelength

Front

The maximum displacement of points on a wave from the rest position

Back

Amplitude

Front

A wave that moves in the same direction as the energy transfer

Back

Longitudinal wave

Front

A wave that moves perpendicular to the direction of energy transfer

Back

Transverse wave

Front

The speed at which a wave travels through a medium

Back

Wave speed

Front

The relationship between wave speed, frequency, and wavelength

Back

Wave speed = frequency × wavelength
