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. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and ...
Mar 20, 2024 · shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure. Shock waves differ from sound waves in that the wave front, in which compression takes place, is a region of sudden and violent ...

Oct 19, 2023 · 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 are caused in supersonic flows. This is when something is traveling at a speed faster than the speed of sound in the medium.

The speed of a shock wave is always greater than the speed of sound in the fluid and decreases as the amplitude of the wave decreases. When the shock wave speed equals the normal speed, the shock wave dies and is reduced to an ordinary sound wave. Jet fighter planes with conical shock waves made visible by condensation.

Sep 12, 2022 · Shock waves are one example of a broader phenomenon called bow wakes. A bow wake, such as the one in Figure 17.9.4 17.9. 4, is created when the wave source moves faster than the wave propagation speed. Water waves spread out in circles from the point where created, and the bow wake is the familiar V-shaped wake, trailing the source.
A 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.
