Video
An object has reached supersonic speed when it travels faster than sound can travel. When it passes through the air, a sonic boom is produced.
When the object flies through the air, sound waves are produced, but they interfere with each other because sound is too slow. The waves combine together to make a loud sonic
BOOM.
If the sound waves come farther apart, would the boom be louder or softer than normal?
The boom would be quieter if the waves came farther apart, because the sound would have more time to catch up, and the waves wouldn't be so bunched together.
The plane in the video broke the sound barrier, meters per second. It flew Mach . Other supersonic aircraft have flown at even higher speeds like Mach , meters per second, and Mach , meters per second. The fastest plane ever flew at about Mach , meters per second.
