Doppler shift in frequency depends upon
(1) the frequency of the wave produced
(2) the velocity of the source
(3) the velocity of the observer
(4) distance from the source to the listener

The intensity of a wave is (a) Proportional to square of the frequency (b) Proportional to the velocity of wave (c) Proportional to the density of the medium (d) Proportional to the square of the distance of the source from the observer

An observer moving towards a stationary source observes that the apparent frequency is three times the actual frequency of the source. If the velocity of sound is V, the velocity of the observer would be-

A source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is
