Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
