A sound sources, detector and a movable wall are arranged as shown in figure. In this arrangement detectir us detacting the maximum intensity. If the speed of sound is 330 m//s in air and frequency of source is 660 Hz , then find the minimum distance by which the wall should be moved away from source, so that detector dtects minimmum intensity.

A listener is at rest and a police siren is moving away from the listerner at 60m/s. what frequency does the listerner hear given that the velocity of sound in air is 340m/s and frequency os siren is 500Hz?

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

There is a source of sound (a tuning fork) moving towards a reflecting wall will a speed of 30 ms^(-1) . The velocity of the sound in air is 330 ms^(-1) and the frequency of the tuning fork is 600 Hz. The observer is between the source and the wall and is moving with some velocity V_(1) towards the wall. The beat frequency heard by the observer is 4 Hz. If the tuning fork is waxed, the frequency beats heard by the observer becomes 3 Hz. If the new frequency of tuning fork is k then k//50 is
