A shock wave, like any wave, is a disturbance moving through a medium. They are thin wavefronts that cause sudden changes in the pressure, temperature, and density of the medium. Shock waves are caused in supersonic flows. This is when something is traveling at a speed faster than the speed of sound in the medium. … Ver mais Before we get to the how, let’s look at the Mach number.
