Two sound sources driven in phase by the same amplifier are d = 5.00 m apart on the y axis, one at y = +2.50 m and the other at y = -2.50 m. At a point a very large distance from the y axis, constructive interference is heard at angles with the x axis of 00 = 0 rad, 01 = 0.140 rad, and 02 = 0.283 rad, and at no angles in between.
