A source producing a sound of frequency 500 Hz is moving towards is listener with a velocity of 30 `ms^(-1)`. The speed of the sound is `330ms^(-1)`. What will be the frequency heard by listener?

A source producing a sound of frequency 90 Hz is approaching a stationary listener with a speed equal to (1/10) of the speed of sound. What will be the frequency heard by the listener?

A source emits a frequency of 1 kHz is moving toward a rest listener with a speed of 0.9 V, where V is the speed of sound wave. The frequency heard by the listener is ________ .

A source producing sound of frequency 170 Hz is approaching a stationary observer with a velocity 17 ms^(-1) . The apparnet change in the wavelength of sound heard by the observer is (speed of sound in air =340 ms^(-1))

Two sources P and Q produce notes of frequency 660 Hz each. A listener moves from P to Q with a speed of 1 ms^(-1) . If the speed of sound is 330 m//s , then the number of beats heard by the listener per second willl be

A source emitting sound at frequency 4000 Hz, is moving along the Y-axis with a speed of 22 m s^-1 . A listener is situated on the ground at the position (660 m, 0). Find the frequency of the sound received by the listener at the instant the source crosses the origin. Speed of sound in air = 330 m s^-1 .

A source emits sound of frequency 600 Hz inside water. The frequency heard in air (velocity of sound in water = 1500 m/s , velocity of sound in air = 300 m/s) will be

A source of sound is moving with a velocity of 50ms^(-1) towards a stationary listener. The listener measures the frequency of the source as 1000Hz. What will be the apparent frequency of the source when it is moving away from the listener after crossing him? (velocity of sound in the medium is 330ms^(-1) ).
