Web21 Mar 2024 · Shock waves are high energy sound waves produced under water with a high voltage explosion and evaporation. In the case of lithotripsy, shock waves are used to dissolve nephrolithiasis while in orthopedic cases they are used to induce neovascularisation at the junction of the tendon-bone and the release of growth factors … WebA sonic boom is the intense sound that occurs as the shock wave moves along the ground. The angle the shock wave produces can be found as sinθ = v vs = 1 M. sin θ = v v s = 1 M. A bow wake is produced when an object moves faster than the speed of a mechanical wave in the medium, such as a boat moving through the water. WebAnswer (1 of 7): I wrote an explanation of this as part of another answer given here: Carey Sublette's answer to Is it possible to create a shockwave without explosion?
