# Wavelength of sound waves

## Description

In the case of longitudinal harmonic sound waves, the wavelength can be calculated by the distance the point has traveled from the wave’s source, the time elapsed, the amplitude of the oscillation, the speed of the wave and the angular frequency of the wave. For sound waves, the amplitude of the wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave.
