Aren't they the same thing?
- actionfromafar 3y agoNot sure about rocket launches but in energetic explosions the shock wave moves faster than sound for a certain distance, until the shock slows down and the sound catches up.
- pixelesque 3y agoDepends.... for (large) explosions, there's initial blast pressure waves which travel faster than the speed of sound.
- NikkiA 3y agoThey don't per se, the precursor wave travels through the ground at the speed of sound in whatever medium (usually rock in nevada tests), which is about 5x the speed of sound in air.
