As an object ... WebThe edge of the cone forms a supersonic wave front with an unusually large amplitude called a "shock wave". When a shock wave reaches an observer a "sonic boom" is heard. [insert N-wave discussion] Unlike ordinary sound waves, the speed of a shock wave varies with its amplitude.
WebAug 9, 2024 · One clarification here is that a sonic boom is produced, continuously, when an object moves at speeds exceeding the speed of sound - not just "on breaking the sound barrier". The effect on the air in front of an object moving at supersonic speeds is different than the effect on the air behind it: the air in front of an object is compressed, the ...
