When a wave moves faster than the local speed of sound ( c s) in a fluid, there is a shock wave since the fluid is unable to respond to the moving wave. Even if velocity ( v) is constant, if pressure ( p) varies, there can be a shock if the local speed of sound is exceeded (i.e. v ≥ c s → M ≥ 1). Therefore, to confirm, isn't ...
