{{Main|Shock wave}}

A shock wave is a type of propagating disturbance. When a wave moves faster than the local [[speed of sound]] in a [[fluid]], it is a shock wave. Like an ordinary wave, a shock wave carries energy and can propagate through a medium; however, it is characterized by an abrupt, nearly discontinuous change in [[pressure]], [[temperature]] and [[density]] of the medium.<ref>
