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 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 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

A car moves towards a hill with speed Vc It blows a horn of frequency f which is heard by an observer following the car with speed Vo The speed of sound in air is V. Find the frequency heard by the observer

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

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

A source of sound is moving towards an observer at rest with a speed V = 0.1 times the speed of sound. Find the apparent freuency as heard by the observer if original frequency is 400 Hz.

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.
