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 m s'1 at an angle of 60° 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 330ms−1), is
  • a)
    106 Hz
  • b)
    97 Hz
  • c)
    100 Hz
  • d)
    103 Hz
Correct answer is option 'D'. Can you explain this answer?

Here, Frequency of source,υ0 = 100 Hz
Velocity of source,vs = 19.4ms−1
Velocity of sound in air,v = 330ms−1
As the velocity of source along the source observer line is vscos60° and the observer is at rest, so the apparent frequency observed by the observer is
