The virtual frequency of a voice is 200Hz while the listener source Towards 40 km / sec Is moving at the speed of When moving away from the source, the virtual frequency is 160Hz. Will have a velocity of (b) 330

The apaarent frequency of a note is 200 Hz when a listener is with a velocity of 40 ms^(-1) towards a stationary source. When he moves away from the same source with the same speed, the apparent frequency of the same note is 160 Hz. The velocity of sound in air in m/s is :

The apparent frequency of a note is 200 Hz when a listener is moving with a velocity of 40 ms​^(-1) towards a stationary source. When he moves away from the same source with the same speed, the apparent frequency of the same note is 160 Hz. The velocity of sound in air (in m/s) is :-

The apparent frequency of a note is 200 Hz. When a listener is moving with a velocity of 40 ms^(-1) towards a stationary source. When he moves away from the same source with the same speed, the apparent frequency of the same note is 160 Hz. The velocity of sound in air in m//s is

A car is moving with a speed of 72 "km-hour"^(-1) towards a roadside source that emits sound at a frequency of 850 Hz. The car driver listens to the sound while approaching the source and again while moving away from the source after crossing it. If the velocity of sound is 340 ms^(-1) , the difference of the two frequencies, the driver hears is

A car is moving with a speed of 72 km-hour^(-1) towards a roadside source that enits sound at a frequency of 850 Hz. The car driver listens to the sound while approching the source and again while moving away from the source after crossing it. If the velocity of sound is 340 ms^(-1) , the difference of the two frequencies the driver hears is

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
