The Doppler Effect and Sonic Boom. When the source of a sound wave is moving relative to the observer who is hearing the wave, there is a shift in apparent frequency heard by the observer. Look at the animation below to get an understanding of the process.

The Doppler effect is an alteration in the observed frequency of a sound due to motion of either the source or the observer. The actual change in frequency is called the Doppler shift. A sonic boom is constructive interference of sound created by an object moving faster than sound.
A sonic boom is a sound associated with the shock waves created by an object traveling through the air faster than the speed of sound. It can be viewed as a Doppler effect on steroids; sonic booms generate an enormous amount of energy and sound like explosions. The first man-made object to ever create this phenomenon was a bullwhip.
Define Doppler effect, Doppler shift, and sonic boom. Calculate the frequency of a sound heard by someone observing Doppler shift. Describe the sounds produced by objects moving faster than the speed of sound. The characteristic sound of a motorcycle buzzing by is an example of the Doppler effect.
Describe the Doppler effect of sound waves; Explain a sonic boom; Calculate the frequency shift of sound from a moving object by the Doppler shift formula, and calculate the speed of an object by the Doppler shift formula
