Phase speed of sound

Applicable units are those of quantitykind:PhaseSpeedOfSound

In a dispersive medium sound speed is a function of sound frequency, through the dispersion relation. The spatial and temporal distribution of a propagating disturbance will continually change. Each frequency component propagates at its own Phase Velocity of Sound.

$c = \frac{\omega}{k} = \lambda f$, where $\omega$ is the angular frequency, $k$ is angular wavenumber, $\lambda$ is the wavelength, and $f$ is the frequency.
