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.
