How are the Doppler effect and sonic boom related?
They both have to do with wave phenomenone. The doppler effect is related to the shift in wavelength experience when a distant light source is coming towards us or away from us. In the former, the wave elnght of light shortens and in the later it lengthens. A sonic boom occurs in when the speed of an aircraft passes the speed of sound in air. In essence, the sound waves made by the jet in subsonic speed project ahead of the aircraft. In supersonic speeds, the sound waves are only found behind the jet. The transition from subsonic to supersonic speeds, creates a huge accumulative wave of sound as all the waves add to each other. This creates the “Boom.
