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 :-

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.

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

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 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 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 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
