A source of sound S emitting waves of frequency 100 Hz and an observer O are located at some distance from each other.The source is moving with a speed of 19.4 ms−1 at an angle of 60o with the source observer line as shown in the figure.The observer is at rest. The apparent frequency observed by the observer (velocity of sound in air 330 ms−1), is

f’=f(vsound/vsound-vsourcecos\Theta)
where \Theta is angle b/w velocitysource vector and line joining source to observer
f’=100 (330/330-9.7) Hz =103.0284108648412Hz
please approve!
