A stationary sound sound 's' of frequency 334 Hz and a stationary ovserver 'O' are placed near a reflecting suface moving away from the source with velocity 2 m/s as shown in the figure. If the velocity of the sound waves is air is v= 330 m/s the apparent frequency of the echo is

A source and an observer approach each other with same velocity 50 m/s. If the apparent frequency is 434 Hz, then the real frequency is (Given velocity of sound = 332 m/s)

An observer and a source both are moving away with velocity 20 m/s each in opposite direction. If frequency of sound observed is 1800Hz then what is actual frequency (velocity of sound= 340 m/s)

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

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 source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is
