๐ซA sonic boom is the sound associated with the shock waves created whenever an object travelling through the air travels faster than the speed of sound.
๐ซSonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.
๐ซSound travels in the form of wave in all directions.
๐ซImagine that a stationary aircraft has its engine ON , so the sound travels like sphere around the aircraft with each outer lining, representing a wave.
๐ซWhen aircraft moves, the waves ahead of aircraft get compressed, but they do not averlap each other below the speed of sound.
๐ซWhen it travels faster than speed of sound, the aircraft travels faster than these waves and the waves combine to form a single high energy wave called Sonic boom.
๐ซThis forms cone behind the aircraft called "Mach Cone".
๐ซWe can't hear the sound when aircraft passes over is , we can only hear it when the base of this cone reaches to us.
๐ซWe sometime can see a cloud form behind the aircraft, this is because of rapid change in air pressure which causes the drop in temperature and water vapor to condense and a cloud forms.
๐ซa critical speed known as Mach 1, and is approximately 1,235 km/h (767 mph) at sea level and 20 °C (68 °F).
