An observer and a source emitting sound of frequency 120 Hz are on the X-axis. The observer is stationary while the source of sound is in motion given by the equation x = 3\sin\omega t ( x inmeters and t in second). If the difference between the maximum and minimum frequencies of the sound observed by the observer is 22 Hz, then the value of ω is (Speed of sound in air = 330 ms^{-1 } )

An observer and a source emitting sound of frequency 120 Hz are on the X-axis. The observer is stationary while the source of sound is in motion given by the equation x=3‌sin‌ω‌t ( x inmeters and t in second). If the difference between the maximum and minimum frequencies of the sound observed by the observer is 22 Hz, then the value of ω is (Speed of sound in air = 330 ms‌−1 )
