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 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 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))

A source of sound of frequency 90 vibrations/ sec is approaching a stationary observer with a speed equal to 1/10 the speed of sound. What will be the frequency heard by the observer

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n_(1) ,the value of n_(1)//n is

A source of sound produces waves of wave length 48cm . This source is moving towards north with speed V//4 where V is speed of sound. The apparent wavelength of the waves to an observer standing south of the moving source will be

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) )
