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. Then the speed of the source will be

The difference between the apparent frequency of a sound of soun 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 300m//s , the velocity of the source is (It is given that velocity of source ltlt velocity of sound )

A source of sound attached to the bob of a simple pendulum execute SHM the difference between the apparent frequency of sound as received by an observer during its approach and recession at the mean position of the SHM motion is 2% of the natural frequency of the source the velocity of the source at the mean position is (velocity of sound in the air is 340m//s ) [Assume velocity of sound source lele velocity of sound in air]

The difference between the apparent frequencies of whistle as received by an observe in rest during approach to recession of the train is 1% . If velocity of sound is 320 m/sec, the velocity of the train is

The apparent change in frequency of a sounding source and observer in relative motion is

At what speed should a source of sound move so that stationary observer finds the apparent frequency equal to half of the original frequency

A listener and a source of sound are moving with the same speed in the same direction. The ratio of the frequency of the source and the frequency which is heard by the listerner is
