When an observer moves away from a stationary source of sound, the apparent pitch will

(A): When an observer moves towards a stationary source, the frequency of sound heard is greater than the actual frequency (R) : Apparent frequency increases because the observer intercepts more number of waves when he moves towards the source.

An observer moves towards a stationary source of sound. The percentage change in the apparent frequency is

When the observer moves towards the stationary source with velocity, v_1 , the apparent frequency of emitted note is f_1 . When the observer moves away from the source with velocity v_1 , the apparent frequency is f_2 . If v is the velocity of sound in air and f_1/f_2 = 2,then v/v_1 = ?

In Dopplers effect, when a source moves towards a stationary observer, the apparent increase in frequency is due to

In Dopplers effect, when a source moves towards a stationary observer, the apparent increase in frequency is due to

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-
