please explain doppler effect

Asked by GARIMA SRIVASTAVA | 12th Mar, 2011, 04:37: AM

Expert Answer:

Dear student
When the source, the medium and the observer are in relative motion, the frequency of sound as received by the observer is different from the frequency of sound emitted by the source. It is known as Doppler's effect.
Hope this helps.
