An observer starts moving with unifrom acceleration a towards a stationary sound soure of frequency f_(o) . As the observer approaches the source ,the apparent frequency f heard by the observer varies with time t as

If an observer is moving with uniform velocity v to wards a stationary source of frequency n, and if the velocity of sound in the medium is V, then the apparent change in the frequency of the sound, heard by the observer, is -

A sound source has frequency f. Source and observer both have same speed.For the apparent frequency observed by observer match the following.

The source producing sound and an observer both are moving along the direction of propagation of sound waves. If the respective velocities of sound, source and an observer are v, v_(s) and v_(0) , then the apparent frequency heard by the observer will be (n = frequency of sound)
