noun

1. Physics. the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.

Idioms

n.1850, “distance between peaks of a wave,” from wave (n.) + length. Originally of spectra; radio sense is attested by 1925. Figurative sense of “mental harmony” is recorded from 1927, on analogy of radio waves. n.

1. The distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest.

1. The distance between one peak or crest of a wave and the next peak or crest. It is equal to the speed of the wave divided by its frequency, and to the speed of a wave times its period.

The distance between crests (or troughs) of a wave.
