shock waven.

Forms: Also ˈshock-wave, ˈshockwave.

Etymology: < shock n.³; compare French onde de choc (common in early 20th-cent. French writings on fluid dynamics).

a. A disturbance that travels through a fluid as a narrow region in which there is a large, abrupt change in pressure and related quantities, esp. one separating regions of subsonic and supersonic fluid flow such as is created by an object moving faster than sound or by an explosion; loosely, any pressure wave of large amplitude.
