Two identical speakers emit sound waves of frequency `680 H_(Z)` uniformly in all directions with a total audio output of `1 mW` each. The speed of sound in air is `340 m//s`. A point `P` is a distance `2.00 m` from one speaker and `3.00 m` from the other.   (a) Finf the intensity `I_(1)` and `I_(2)` from rach speaker at point `p` separately.  (b) If the speakers are driven coherently and in phase, what is the intensity at point `p`?  (c ) If they driven coherently but of phase by `180^(@)`, what is the intensity at point `P`?  (d) If the speakers are incoherent, what is the intensity at point `p`?
