A source of frequency n is moving with a uniform velocity v towards a stationary observer. If the velocity of sound is V, then the change in frequency would be -

If a source of frequency n crosses a stationary observer with uniform velocity v and if the velocity of sound V gt gt v , then the change in the frequency due to Doppler effect would be -

If an observer moving with velocity v crosses a stationary source of frequency n, then the change in the frequency would be -

If an observer is moving with uniform velocity v to wards a stationary source of frequency n, and if the velocity of sound in the medium is V, then the apparent change in the frequency of the sound, heard by the observer, is -

If a source of frequency n moving with velocity v crosses a stationary observer, then the change in the frequency of sound heard by the observer will be (velocity of sound = V)

When a source of frequency n is receding away from a stationary observer with velocity v, then the apparent change in frequency due to Doppler’s effect is found to be Delta n_(1) and when the observer is reducing from a stationary source with the same velocity v, then the apparent change in frequency is Delta n_(2) , then -

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n_(1) ,the value of n_(1)//n is

A source of frequency 1 kHz is moving towards a stationary observer with velocity of 0.9 times that of sound. What is the frequency heard by the observer ?

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)
