An ambulance is traveling down a highway at `34.5 ms^(-1)`. The ambulance having siren emits sound of frequency 380 Hz. If a passenger in a car travelling with the speed of `26.4 ms^(-1)` in the opposite direction as the car approaches the ambulance and after the two vehicles passed each other, then find the frequency heared by that passenger.
Take speed of sound in air is `343 ms^(-1)`

At what speed should a car approach a stationary observer if the hears the music of the car radio with a frequency 20% higher than it actully is ? The speed of sound is 340 ms^(-1)

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15 ms^(-1) Then, the frequency of sound that the observer hears in the echo reflected from the cliff is

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15 ms^-1 Then , the frequency of sound that the observer hears in the echo reflected from the cliff is:

A sound wave travels with a speed of 330 ms^(-1) in air. If the wavelength of the wave is 330 cm, then the frequency of the wave is ______

An ambulance blowing a siren of frequency 700 Hz is travelling towards a wall with a speed 2 m(s)^-1.Calculate the number of beats heard in one second by the driver of the ambulance.(velocity of sound = 350 m(s)^-1 )

A source of sound emitting sound with frequency 540Hz approaches a staionary observer with a speed of 30 ms^-1 . If velocity of sound is taken as 330 ms^-1 , the frequency as heard by the observer will be

Two cars are approaching each other on a straight road and moving with a velocity of 30 kmh-1 . If the sound produced in a car is of frequency 500 Hz, what will be the frequency of sound as heard by the person sitting in the other car ? When the two cars have crossed each other and are moving away from each other, what will be the frequency of sound as heard by the same person ? Speed of sound= 330 ms^-1 .
