wavelength

Definition

Wavelength is the distance between two consecutive crests of a wave. It is measured in meters. Wavelength is important because it determines how fast the wave travels and how much energy it carries.

For example, the wavelength of a sound wave determines how high or low the pitch of the sound is. The shorter the wavelength, the higher the pitch.

How can the word be used?

The wavelength of sound is the distance between two successive compressions of the sound wave.
