The distance between corresponding points on two successive waves, and therefore the length of a complete cycle of a wave.
The distance between corresponding points on two successive waves, and therefore the length of a complete cycle of a wave. For visible light, wavelengths are as small as a few hundred nanometers. The wavelength of sound in air, at frequencies we can hear, ranges from a few centimeters to almost 20 meters.
