A shockwave is a sudden and powerful movement or disturbance that travels through the air, often causing damage or disruption.
When we talk about shockwaves, usually we're referring to something big happening - an explosion, a crash, or a natural disaster. Imagine you're standing near a firework going off, and suddenly there's a loud boom followed by a strange buzzing feeling in the air. That's basically what a shockwave is: a wave of energy that spreads out from the source of the disturbance. It can be intense enough to knock people over or break things, so it's not something you want to be around when it happens. You might hear about shockwaves on the news when there's a big earthquake or a plane crashes into a building.
A powerful compression wave produced by the movement of a body through a fluid or gas at a velocity greater than the local speed of sound.
