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 X and f respectively. The apparent frequency and wavelength recorded by the observer are respectively

Speed of sound wave in air

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 (Take velocity of sound in air = 330 ms^(-1) )

To hear the echo distinctly,will the distance from the source of sound to the reflecting surface be same at all temperatures? Explain your answer.

Answer the following : If sound waves are generated in air, what moves away from the source? Is it the air itself or the state of compression and rarefaction created in the air?

Two sources A and B are sounding notes of frequency 680 Hz. A listener moves from A to B with a constant velocity u. If the speed of sound is 340 m/s, What must be the value of u so that he hears 10 beats per second?

The observer is moving with velocity 'v_0' towards the stationary source of sound and then after crossing moves away from the source with velocity ' v_0 '. Assume that the medium through which the sound waves travel is at rest, If 'v' is the velocity of sound and 'n' is the frequency emitted by the spurce then the difference between apparent frequencies heard by the observer is

At a place due to beats obtained from two sources of sound

Assertion: The whistle of an approaching engine appears to be shriller than that of a receding engine. Reason: This is due to Doppler effect, which states that if a source of sound approaches the observer, the frequency of sound increases and if the source recedes the observer, the frequency of sound decreases.

A source of sound S is moving with a velocity 50 m//s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of sound in the medium is 350 m//s .
