An observer is moving away from a source of sound of frequency 100 Hz at aspeed of `33ms^-1`. If the spped of the sound in air is `330ms^-1` and the observed frequency is

An observer is moving away from source of sound of frequency 100 Hz. His speed is 33 m/s. If speed of sound is 330 m/s, then the observed frequency is

An observer is moving away from a sound source of frequency 100 Hz. If the obsever is moving with a velocity 49ms^-1 and the speed of sound in air is 330ms^-1 . The observed frequency is

There is a source of sound (a tuning fork) moving towards a reflecting wall will a speed of 30 ms^(-1) . The velocity of the sound in air is 330 ms^(-1) and the frequency of the tuning fork is 600 Hz. The observer is between the source and the wall and is moving with some velocity V_(1) towards the wall. The beat frequency heard by the observer is 4 Hz. If the tuning fork is waxed, the frequency beats heard by the observer becomes 3 Hz. If the new frequency of tuning fork is k then k//50 is

A source producing a sound of frequency 500 Hz is moving towards is listener with a velocity of 30 ms^(-1) . The speed of the sound is 330ms^(-1) . What will be the frequency heard by listener?

The difference between the apparent frequency 71. of a source of sound as perceived by the observer during its approach and recession is 2% of the frequency of the source. If the speed of sound in air is 300 ms^(-1) , then the velocity of the source is

The difference between the apparent frequency of a source of sound as perceived by the observer during its approach and recession is 2% of the frequency of the source. If the speed of sound in air is 300 ms^(-1) , the velocity of the source is

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
