=== Acoustic waves ===
{{Main|Acoustic wave}}

Acoustic or [[sound]] waves are compression waves which travel as body waves at the speed given by:
: <math> v = \sqrt{\frac{B}{\rho_0}}, </math>
or the square root of the adiabatic [[bulk modulus]] divided by the ambient density of the medium (see [[speed of sound]]).
