shock wave(redirected from Shockwaves)
Also found in: Thesaurus, Medical, Encyclopedia.
1. A large-amplitude compression wave, as that produced by an explosion or by supersonic motion of a body in a medium.
2. A severe disruption, disturbance, or reaction: The bad news sent shock waves through the stock market.
1. (General Physics) a region across which there is a rapid pressure, temperature, and density rise, usually caused by a body moving supersonically in a gas or by a detonation. Often shortened to: shock See also sonic boom, shock tube
2. a feeling of shock, horror, surprise, etc that affects many people as it spreads through a community
3. (Civil Engineering) the effect created on a queue of moving cars in the lane of a motorway when one car brakes suddenly and the cars behind have to brake as well, causing cars to slow down, sometimes for miles behind the first braking car
1. a region of abrupt change of pressure and density moving as a wave front at or above the velocity of sound.
2. a repercussion from a startling event.
A large-amplitude wave formed by the sudden compression of the medium through which the wave moves. Shock waves can be caused by explosions or by objects moving through a fluid at a speed greater than the speed of sound. Because the waves generated in the fluid by the rapid movement cannot move at a speed greater than the speed of sound (thereby keeping pace with the object that caused them to form), they pile up and become compressed together.
The continuously propagated pressure pulse formed by the blast from an explosion in air, under water or under ground. See also blast wave.

|Noun||1.||shock wave - a region of high pressure travelling through a gas at a high velocity; "the explosion created a shock wave"|
sonic boom - an explosive sound caused by the shock wave of an airplane traveling faster than the speed of sound; "a sonic boom follows an aircraft as a wake follows a ship"
