The difference between the apparent frequency of a source of sound as perceived by an observer during its approach and recession is 2% of the natural frequency of the source. If the velocity of sound in air is 300 m/sec, the velocity of the source is (It is given that velocity of source << velocity of sound)
Text Solution
Verified by ExpertsThe correct answer is:
B
When the source approaches the observer
Apparent frequency 
= 
(Neglecting higher powers because v S << v)
When the source recedes the observed apparent frequency
