Shock wave - Wikipedia
网页In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium.
Shock wave | Definition & Facts | Britannica
网页2024年9月6日 · Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by phenomena that create violent changes in pressure. Shock waves differ from sound waves in that the wave front is a region of sudden and violent change.

网页2022年10月18日 · Shockwave therapy can offer such help, jump-starting the body’s ability to regenerate new tissue. It also decreases your pain by directly stimulating your nerves at the site of the injury.
Shock Waves – The Physics Hypertextbook
网页The shock wave from a supersonic object is a cone composed of overlapping spherical wavefronts. As any one of these wavefronts forms, it propagates radially outward at speed c and acquires a radius ct. At the same time the source, traveling at speed v …
What Are Shock Waves And How Are They Created?
网页2023年10月19日 · What Is A Shock Wave? 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 | How Things Fly - Smithsonian Institution
网页What is a Shock Wave? When an airplane travels less than the speed of sound, the air ahead of it actually begins to flow out of the way before the plane reaches it. The pressure waves created by the airplane passing through the air end up being smooth and gradual.
17.8 Shock Waves - University Physics Volume 1 - OpenStax
网页This superposition forms a disturbance called a shock wave, a constructive interference of sound created by an object moving faster than sound. Inside the cone, the interference is mostly destructive, so the sound intensity there is much less than on the shock wave.
