A source and an observer move away from ...

A source and an observer move away from each other with a velocity of 10 m/s with respect to ground. If the observer finds the frequency of sound coming from the source as 1950 Hz , then actual frequency of the source is (velocity of sound in air = 340 m/s )

1950 Hz

2068 Hz

2132 Hz

2486 Hz

Text Solution

Verified by Experts

The correct Answer is:

`f.=f((v-v_(o))/(v+v_(s)))`
`implies 1950=f((340-10)/(340+10))`
`implies f=1950xx(350)/(330)=2068Hz`.

A source emits a frequency of "290Hz" .An observer is moving away from the source with a velocity "20ms^(-1)" and the source is moving away from the observer with a velocity "10ms^(-1)" .The wind is blowing in a direction from the observer to the source with a velocity "5ms^(-1)" .The apparent frequency heard by the observer is (Velocity of sound in air "=343ms^(-1)" )

On the same path, the source and observer are moving such a way that the distance between these two inicreases with the time. The speeds of source and observer are same and equal to 10ms^(-1) with respect to the ground while no wind in blowing. The apparent frequency received by observer is 1950 Hz then the original frequency must be (the speed of sound in present medium is 340 m//s
