Quizplus · Accepted Answer

A shock wave is a type of pressure wave that is formed when an object moves faster than the speed of sound in air. This creates a supersonic flow regime, where the air molecules cannot move out of the way of the object fast enough, causing a compression of air particles and a build-up of pressure. This pressure wave is what we experience as a sonic boom, and is what creates the distinctive sound associated with supersonic flight.
