In going through the sound barrier a sonic boom is created ..If it were possible to go HYPERSONIC... 5 times the speed of sound, would a boom still be created?
The sonic boom occurs as you go through the sound barrier. Any speed - supersonic, hypersonic etc will pass through this speed at a particular point and that is when the boom is created.
This shock wave eminates from the object moving through the air at the speed of sound in the shape of a cone which narrows (becomes more pointed) as speed increases.
