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 od 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 19.4 ms^-1 at an angle of 60^@ with the source observe line as shwon in the figure. The observer is at rest. The apparent frequency observed by the observer (velocity of sound in air 330 ms^-1 is:

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 source of sound is moving away from an observer at rest with a velocity of 50 m s^(-1) . If the frequency of sound is 200 Hz , find the apparent frequency observed by the observer. (Take velocity of sound = 300 m s^(-1))

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)" )

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 )
