A small source of sound moves on a circle as shown in fig. and an observer is sitting at O. Let at v_1,v_2,v_3 be the frequencies heard when the source is at A, B and C respectively.

A small source of sound moves on a circle as shown in the figure and an observer is standing on O. Let n_1 , n_2 and n_3 be the frequencies heard when the source is at A, B and C respectively. Then

A small source of sound moves on a circle as shown in the figure and an observer is standing on O. Let n_1 , n_2 and n_3 be the frequencies heard when the source is at A, B and C respectively. Then

A small source of sound moves on a circle of radius r with constant speed V_s . eta is the actual frequency of the source. For the positions of the source indicated in the figure find the frequency as heard by three observers at the points P,O & Q respectively

The source (S) of sound is moving constant velocity v_(0) as shown in diagram. An observer O listens to the sound emmited by the source. The observed frequency of the sound
