How do Sonic Booms work? Y’know, when an aircraft breaks the sound barrier and produces an audible explosion. I assume it must have something to do with sound waves no longer being able to travel forward from the travelling craft and bursting back past the nose of the craft. Is the sound influenced by the shape of the aircrafts nose?
But what puzzles me even more is that (unless I’m misinformed about this) you get repeated booms every time the aircraft goes through different stages. i.e. MACH1, MACH2 etc. How does that work, cos I can think of no logic explanation for this latter phenomena?
