When an observer moves towards a stationary source, then the apparent pitch will

An observer is moving towards the stationary source of sound, then

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

An observer moves towards a stationary source of sound, with a velocity one-fifth of the velocity of sound. What is the percentage increase in the apparent frequency?

An observer moves towards a stationary source of sound, with a velocity one-fifth of the velocity of sound. What is the percentage increase in the apparent frequency?

(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.
