A source is moving towards an observer with a speed of 20 m / s and having frequency of 240 Hz . The observer is now moving towards the source with a speed of 20 m / s . Apparent frequency heard by observer, if velocity of sound is 340 m / s , is

If the source is moving away from the observer, then the apparent frequency …………..

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 source is moving towards a stationary observer, so that the apparent frequency increases by 50%. If velocity of sound is 330 m/s, then velocity of source is

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 )

If a source emitting waves of frequency f moves towards an observer with a velocity (v)/(4) and the observer moves away from the source with a velocity (v)/(6) , the apparent frequency as heard by the observer will be (v=velocity of sound)

In the absence of air source and observer moves away 20 m/s. The frequency observed by the observer is 1800 Hz and velocity of sound in air is 340 m/s then find original frequency of source
