A siren placed at a railway platform is emitting sound of frequency 5 kHz. A passenger sitting in a train 'A' going out of platform records frequency 4.5kHz. During return journey in a different train ' B' he records a frequency of 6kHz ratio of the velocity of train 'B' and train 'A' is
(Given velocity of sound,`V=340m`/`sec`)

A siren placed at a railway platform is emmitting sound of frequency 5 kHz . A passenger sitting in a moving train A records a frequency of 5.5kHz while the train approaches the siren. During his return journey in a different train B he records a frequency of 6.0 kHz while approaching the same siren. the ratio the velocity of train of A is

Two trains A and B are approaching a platfrom from opposite directions .The siren in the station is making a sound at a frequency 4kHz.The passengers in trains A and B hear siren at frequencies 4.5 and 5kHz respectively.Then the velocities of the trains A and B are (velocity of sound in air =340 m/s)

Apparent frequency of train A is heard by observer in train B as 3/4 of the true frequency. Find the value of velocity of train B in m/sec. taking train A to be stationary. If the sound velocity is 332 m//sec .-

A man standing on a platform hears the sound of frequency 604 Hz coming from a frequency 550 Hz from a train whistle moving towards the platform. If the velocity of sound is 330 m/s, then what is the speed of train?

An observer standing at station observes frequency 219 Hz when a train approaches and 184 Hz when train goes away from him. If velocity of sound in air is 340m//s , then velocity of train and actual frequency of whistle will be

An engine of a train is moving towards a platform with a velocity of 100 m s^(-1) . If the frequency of sound produced is 200 Hz , find the apparent frequency of the sound as observed by an observer standing on the platform (Taking velocity of sound = 320 m s^(-1) ) .

An observer standing on a railway crossing receives frequencies 2.2 kHz and 1.8 kHz when the tran approaches and recedes from the observer. Find the velocity of the train (speed of sound in air is 300 m/s).

A train is passing a stationary observer at station with constant velcity. If the frequency observed by the person during its approches and recession are 2.2 kHz and 1.8 kHz respectively. Then find the velocity of train if the velocity of sound in air in air is 300 m//s .
