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)

1.	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)
