#Dopplers_effect The apparent change in frequency of wave due to the relative motion between source and observer is called Dopplers effect.When source and observer move,there is change in velocity of wave.And when source moves towards observer,there is change in no. of waves of frequency.It causes change in frequency for observer.When source and observer approach each other,there is increase in apparent frequency but if they are moving away,there is decrease in apparent frequency.
