If the relative motion between the source and observer is to separate them more with time,
the apparent frequency is lower than actual frequency.
Doppler’s shift: The change in the frequency ( υ ) and apparent frequency of sound heard
(υ 1 ) is called Doppler’s shift.

Dear Students,

This is a final warning to all of you as not to copy paste the exact answer that has already been posted earlier. You all will not get points to these answers and these points will be forefeited.

Thanks

The Doppler effect (or Doppler shift) is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source. It is named after the Austrian physicist Christian Doppler, who proposed it in 1842 in Prague.
