A source of sound emitting waves at 360 H_(Z) is placed in front of a vertical wall, at a distance 2 m from it. A detector is also placed in front of the wall at the same distance from it. Find the minimum distance between the source and the detestor for which the detector detects a maximum of sound. Take speed of sound in air = 360 m//s . Assume that there is not phase change in reflected wave.

Why will an echo not be heard when the distance between the source of sound and the reflecting surface is 10 m ?
