Shock waves are produced when a projectile flies supersonically in the air. In wind tunnel experiment, it has been observed that as a steady supersonic flow moves past a conical object, a conical shock is produced around the conical object, attached to the head if such object has a sharp pointed tip, otherwise, the … state why the skin is an organWebThe angle of the shock wave can be found from the geometry. In time t the source has moved v s t and the sound wave has moved a distance vt and the angle can be found using sin θ = v t v s t = v v s. Note that the Mach number is defined as v s v so the sine of the angle equals the inverse of the Mach number, sin θ = v v s = 1 M. 17.22 state wide autos llc
