A source of sound S emitting waves of frequency 100 Hz and an observer O are located at some distance from each other. The source is moving with a speed of 19.4ms^-1 at an angle of 60^(@) with the source observer line as shown in the figure. The observer is at rest. The apparent frequency observed by the observer (velocity of sound in air 330ms^-1 ) is

A source is approaching towards an observer with constant speed along the line joining them. After crossing the observer, source recedes from observer with same speed. Let f is apparent frequency heard by observer. Then,

A source and an observer are moving towards each other with a speed equal to v/2 where v is the speed of sound. The source is emitting sound of frequency n . The frequency heard by the observer will be

A source of frequency 'f' is stationary and an obsercer starts moving towards it at t=0 with constant small acceleration. Then the variation of observed frequency 'f' registered by the observer with time is best represented as

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 wave of frequency f propagasing through air with a velocity C , is reflected from a surface which is moving away from the source with a constant speed V . Find the frequency of the reflected wave, measured by the observer at the position of the source.

The source producing sound and an observer both are moving along the direction of propagation of sound waves. If the respective velocities of sound, source and an observer are v, v_(s) and v_(0) , then the apparent frequency heard by the observer will be (n = frequency of sound)

If a source of frequency n moving with velocity v crosses a stationary observer, then the change in the frequency of sound heard by the observer will be (velocity of sound = V)
