If a source emitting waves of frequency f moves towards an observer with a velocity `(v)/(4)` and the observer moves away from the source with a velocity `(v)/(6)`, the apparent frequency as heard by the observer will be (v=velocity of sound)

A source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is

A source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is

A source emits a frequency of "290Hz" .An observer is moving away from the source with a velocity "20ms^(-1)" and the source is moving away from the observer with a velocity "10ms^(-1)" .The wind is blowing in a direction from the observer to the source with a velocity "5ms^(-1)" .The apparent frequency heard by the observer is (Velocity of sound in air "=343ms^(-1)" )

When the observer moves towards the stationary source with velocity, v_1 , the apparent frequency of emitted note is f_1 . When the observer moves away from the source with velocity v_1 , the apparent frequency is f_2 . If v is the velocity of sound in air and f_1/f_2 = 2,then v/v_1 = ?

When the observer moves towards the stationary source with velocity, v_1 , the apparent frequency of emitted note is f_1 . When the observer moves away from the source with velocity v_1 , the apparent frequency is f_2 . If v is the velocity of sound in air and f_1/f_2 = 2,then v/v_1 = ?

When the listener moves towards a stationary source with a velocity V_(L) , the apparent frequency of a note emitted by the source is f' . When the listener moves away from the source with the same velocity, the apparent frequency of the note is f" . Given f'//f"=3 and V as the velocity of sound in air, the value of V/V_(L) is

When the listener moves towards a stationary source with a velocity v_(1) m the apparent freqency of a note emitted by the source is f' When the listener moves away from the source with the same velocity, the apparent frequency of the note f/f'=3. If v the velocity of sound in air, the value of v//v_(1) is -

When the observer moves towards the stationary source with velocity, 'V_1' , the apparent frequency of emitted note is ‘F_1' . When the observer moves away from the source with velocity ‘V_1’ , the apparent frequency is 'F_2' . If 'V' is the velocity ofsound in air and frac(F_1)(F_2)=2 then frac(V)(V_1)= ?
