    2. The speed of sound in air is 345 m/s. (7 pts) (a) Speakers A and B operate from the same transmitter and therefore emit sound waves in phase. The frequency of the sound waves is 115 Hz. Speaker B is 6.00 m to the right of speaker A and point P is 13.5 m to the right of speaker B, as shown in the sketch. Is the interference at P constructive or destructive? 6m . 13.5m Ans. constructive

    Two speakers are separated by two meters in a plane. They are in-phase. They project 891 Hz sound waves. The speed of sound is 343 m/s. Consider the point 5.0 m in front of one of the speakers, perpendicular to the plane of the speakers. At this point, is there maximum constructive interference, perfect destructive interference, or something in between?
