Sound Wavelength


Wavelength is the distance between repeating units of a propagating wave of a given frequency.
Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through. Sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water.
(For sound waves in air, the speed of sound is 343 m/s (at room temperature and atmospheric pressure). The wavelengths of sound frequencies audible to the human ear (20 Hz–20 kHz) are thus between approximately 17 m and 17 mm, respectively.)
