The physics of a sonic boom.

irplane travels through the air, it produces sound waves. If the plane is traveling slower than the speed of sound (the speed of sound varies, but 1200kph is usual at sea level), then sound waves can ... d waves can move ahead of the plane.If the plane breaks the sound barrier and flies faster than the speed of sound, it produces a sonic boom when it flies past. The boom is the "wake" of the plane's s ...
