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

An observer moves towards a stationary source of sound with a speed 1/5 th of the speed of sound. The wavelength and frequency of the source emited are lamda and f, respectively. The apparent frequency and wavelength recorded by the observer are, respectively- (a) f,1.2 lambda (b) 0.8f,0.8lambda (c) 1.2f,1.2lambda (d) 1.2f,lambda

An observer moves towards a stationary source of sound with a speed ((1)/(5)) th of the speed of sound. The wavelength and frequency of the source emitted are lamda and f, respectively. The apparent frequency and wavelength recorded by the observer are, respectively.

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?

An engine giving off whistle is moving towards a stationary observer with 50m/s speed. What will be the ratio of the frequencies of the whistle heard when engine is approaching and receding from the observer? (speed of sound = 350 m/s)

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is 25% more that the actual frequency. If the speed of sound is v, that of the source is

a bus is moving towards and stationary observer with speed 20 m/s blows a horn of frequency 200 Hz. the frequency of sound heard by the observer is approximately ( take speed of sound 320 m/s)
