wavelength wave·length (wāv’lěngkth’, -lěngth’)
Symbol λ The distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest.
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.
