Shock wave condition in traffic

Weblost-contact.mit.edu WebThe speed of a shock wave is always greater than the speed of sound in the fluid and decreases as the amplitude of the wave decreases. When the shock wave speed equals the normal speed, the shock wave dies and is reduced to an ordinary sound wave. Jet fighter planes with conical shock waves made visible by condensation.
