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)

when a source of sound of frequency f crosses stationary observer with a speed v_(s) (lt lt speed of sound v) , the apparent change in frequency Δf is given by

Assertion : A sound source is approaching towards a stationary observer along the tine joining them. Then , apparent frequency to the observer will go on increasing. Reason : If there is no relative motion between source and observer , apparent frequency is equal to the actual frequency.

An observer is moving towards the stationary source of sound, then A. Apparent frequency will be less than the real frequency B. Apparent frequency will be greater than the real frequency C. Apparent frequency will be equal to real frequency D. Only the quality of sound will change
