For the speed of sound in air, use v = 339 m/s. Two speakers stand against a vertical wall, distance 2.44 m apart, and they produce coherent sound waves of frequency 1,905 Hz. You are sitting in the center of a long couch parallel to the wall and 3.44 m from it. Each speaker is the same distance from you. How far along the couch, in cm, would you have to slide to reach the first point of minimum sound?
