A source S emitting sound of frequency f moves uniformly along a straight line wit a velocity u as shown The velocity of sound in the medium is v u Two detectors D and D are placed on the line perpendicular to line of motion of S Point P one represents the point of closest approach of S to the detectors The frequency detected f by D and D versus time t graph is shown on the same graph paper fp NARA S u P D D Choose the incorrect option s A Graph 1 belongs to detector D fo Graph 2 Graph 1 B t to is the instant when source S is at P C The value of f is f D The value of f is Graph 1 Graph 2
