A source of sound S emitting waves of frequency 100 Hz and an observor 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 60° with the source observer line as shown in the figure. The observor is at rest. The apparent frequency observed by the observer is (velocity of sound in air 330 ms-1)
  • a)
    103 Hz
  • b)
    106 Hz
  • c)
    97 Hz
  • d)
    100 Hz
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A source of sound S emitting waves of frequency 100 Hz and an observor...
Here, original frequency of sound, f0 = 100 Hz
Speed of source Vs = 19.4 cos 60° = 9.7

19.4 cos 60° = 9.7
From Doppler's formula

Apparent frequency f1 = 103 Hz
