explosion is called sonic boom sonic boom sonic or audible component of the wave shock caused by an aircraft when the speed exceeds Mach 1 (speed of sound). It is frequently seen in military aircraft, but also can cause civilian aircraft, including the now decommissioned Concorde, capable of reaching Mach 2.03, or Space Shuttle, reaching Mach 27.
The phenomenon is related to the Doppler effect , which describes the changes in the frequency perceived by an observer when he or sound emitting source is moving. As you read and understand this effect in sound waves, the question arises about what will happen as often perceived as the source velocity approaches, travel and exceed the speed of sound.
The effect produces some beautiful images:
This is hardly the Thrust SSC in elmomento breaking the sound barrier on wheels in 1997. The pileup is about 110000 ... But that is another story ....
