A source of frequency 'f' is stationary and an obsercer starts moving towards it at t=0 with constant small acceleration. Then the variation of observed frequency 'f' registered by the observer with time is best represented as

A source emitting a sound of frequency f is placed at a large distance from an observer. The source starts moving towards the observer with a uniform acceleration a. Find the frequency heard by the observer corresponding to the wave emitted just after the source starts. The speed of sound in the medium is v.

Two identical source moving parallel to each other at seperation 'd' are producing sounds of frequency 'f' and are moving with constant velocity v_(0) . A stationary .observer 'O' is on the line of motion of one of the sources. Then the variation of beat frequency heard by O with time is best represented by: (as they come from large distance and go to a large distance)

A source emitting a sound of frequency v is placed at a large distance from an observer. The source starts moving towards the observer with a uniform acceleration a. Find the frequency heard by the observer corresponding to the wave emitted just after the source starts. The speed of sound in the medium is v.
