A source of sound producing wavelength 50 cm is moving away from a stationary observer with `(1/5)^(th)` speed of sound. Then what is the wavelength of sound received by the observer?

A source of sound producing wavelength 60cm is moving away from a stationary observer, with speed (1)/(4)th of speed of sound. Then the wavelength of sound hear by the observer is

A source producing sound of frequency 340 Hz is moving away from a stationary observer with a velocity of 34 ms^(-1) . The apparent change in wavelength of sound heard by the observer is (V = 340 ms^(-1))

When a source of sound moves towards stationary observer,the wavelength of sound received by the observer

A sound source is moving towards a stationary observer with 1/10 of the speed of sound. The ratio of apparent to real frequency 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))

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 )

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) )
