A car moves towards a hill with speed v_(c) .It blows a horn of frequency f which is heard by an observer following the car with speed s .The speed of sound in air is v . find frequency heard by the observer.

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n_(1) ,the value of n_(1)//n is

The source of sound generating a frequency of 3 kH z reaches an observer with a speed of 0.5 times the velocity of sound in air. The frequency heard by the observer is

If source and observer both are relatively at rest and if speed of sound is increased then frequency heard by observer will

A source of sound of frequency 90 vibrations/ sec is approaching a stationary observer with a speed equal to 1/10 the speed of sound. What will be the frequency heard by the observer

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
