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)
The difference between the apparent frequency of a source of sound as perceived by the stationary observer during its approach and recession is 2% of the frequency of the source. If the speed of sound in air is 300ms−1 the velocity of the source is
