Question
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
The angle 
at which he will hear maximum intensity for first time?
- 2o
- 1 0o
- 1 6o
- 25o
The correct answer is: 1 6o
