Four point sources each of frequency (f) are fixed at their position as shown in the figure. An observer moving with constant velocity $V$ is crossing origin. ' N ' is number of different frequencies observed by the observer at the moment when it is crossing origin.

Options:(select one or more)

Answer:

A,C,D

Solution:

(A) $f_{1} > f f_{2} = f_{4} = f f_{3} < f$

(B) $f_{1} = f_{2} > f f_{3} = f_{4} < f$

(D) $f_{1} = f_{2} > f$
