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

In the figure shown a source of sound of frequency 510 Hz moves with constant velocity v_(S) = 20 m//s in the direction shown. The wind is blowing at a constant velocity v_(W) = 20 m//s towards an observer who is at rest at point B . The frequency detected by the observer by corresponding to the sound emitted by this source at initial position A , will be (speed of sound relative to air = 330 m//s ).

Velocity of sound is v. Source and observer move towards each other with velocities V_(s) and V_(0) respectively. Wind is blowing with a velocity v_(m) in the direction opposite to the propagation of sound, n is the frequency of the sound. The apparent frequency of the sound heard by the observer is :-

A source of sound is moving with a velocity of 50 ms ^(-1) towards a stationary observer.The observer measures the frequency of sound as 500 Hz.The apparent frequency of sound as heard by the observer when source is moving away from him with the same speed is (Speed of sound at room temperature 350 ms ^(-1)

A source of sound is moving with a velocity of 50ms^(-1) towards a stationary observer . The Observer measure the frequency of sound as 500Hz. The appartment frequency of sound as heard by the observer when source is moving away from hom with the same speed is (Speed of sound at room temperature 350ms^(-1)
