If a source sounding a whistle with a constant frequency moves in a circle and frequencies observed by observer O, when the source is at points `A, B, C be ν_(a)a​, ν_(​b)​, ν_(​c)`​ then :-

A

`v_(a) gt V_(b) gt v_(c ) `

B

` v_(a) lt v_(b) lt v_(c ) `

C

`V_(a) = v_(c ) gt v_(b ) `

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
B

At point a Component of veloity is away from observer
At point B component of velocity along the line
joining source & the observer is zero ,At C.
Component of velocity is towards the observer .

If a source sounding a whistle with a constant frequency moves in a circle and frequencies observed by observer O, when the source is at points A, B, C be v_(a) , v_(b) , v_(c) ,then

A sound source has frequency f. Source and observer both have same speed.For the apparent frequency observed by observer match the following.

The velocity of source of sound when the frequency appears to be double the actual frequency of stationary observer will be

When the source is moving towards the stationary observer, the apparent frequency is given by

A sound source is moving with speed 50 m//s towards a fixed observer. Frequency observed by observer is 1000Hz . Find out apparent frequency observed by observer when source is moving away from observer (Speed of sound =350 m//s )

A sound source moving with speed 50 m/s along x-axis and observer at rest on y-axis.If the frequency observed by observer when source crosses the origin is 96 Hz, then the original frequency of source is :(speed of sound is given medium is 200 m/s)

A small source of sound moves on a circle as shown in figure and an observer is sitting at O. Let v_1,v_2,v_3 be the frequencies heard when the source is at A,B and C respectively. .

A small source of sound moves on a circle as shown in the figure and an observer is standing on O. Let n_1 , n_2 and n_3 be the frequencies heard when the source is at A, B and C respectively. Then
