Two speakers S1 & S2 driven by the same amplifiers are placed at y=1m and y=-1m. The speakers vibrate in phase at 600 Hz. A man stands at a point on x-axis at a very large distance form the origin and starts moving parallel to y-axis. The speed of sound in air is 330 m/s
If he continous to walk along the same line how many more maxima can he hear
