The distance from one point on a vibrating wave to the same point on the next wave. The lengths of the sound waves (wavelengths) we can hear range from one inch to 40 feet. High frequency sounds have short wavelengths (and are more directional), low frequency sounds have long wavelengths (and are less directional). In lighting terms, blue light is short wavelength, green is medium and red is long wavelength. Beyond visible light are the short wavelength Ultra Violet light and the long wavelength Infra Red light. See also Frequency.

The distance between any two corresponding points on a wave. See also: frequency, Advanced Topics

The distance between wave crests in any type of wave.

The length of a Soundwave, For example , sound at 50Hz in air has a Wavelength of around 6.9m.

The length from one point on a wave to the point where it is repeated exactly in space, at a given time.

The length of a wave. Sound at 50Hz in air has a wavelength of around 6.9 metres.
