A source of sound S having frequency f. Wind is blowing from source to observer O with velocity u. If speed of sound with respect to air is C, the wavelength of sound detected by O is :

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

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))

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

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

In the case of sound waves, wind a blowing from source to reciver with speed U_(W) . Both source and receiver are stationary.If lambda_(0) is the original wavelength with no wind and V is speed of sound in air then wavelength as received is given by :
