Question
Two speakers 
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 from the origin and starts moving parallel to y - axis. The speed of sound in air is 330 m/s. The angle q at which he will hear maximum intensity for first time?
- 2o
- 10o
- 16o
- 25o
The correct answer is: 16o
