Sonic Boom - Breaking the Sound Barrier

The video explains the phenomenon of Sonic booms, which occur when an object like a fighter jet travels faster than the speed of sound, creating a loud noise due to compressed sound waves forming a shockwave. It discusses how the speed of sound varies in different mediums, being slowest in gases and fastest in solids. The video also describes the visual effects, such as vapor clouds, that can occur when a jet breaks the sound barrier.
