Two loudspeakers `S_(1)` and `S_(2)` each emit sounds of frequency `220 H_(Z)` uniformly in all directions. `S_(1)` has an acoustic output of `1.2 xx 10^(-3) W` and `S_(2)` has `1.8 xx 10 ^(-3) W` . `S_(1)` and `S_(2)` vibrate in phase.Consider a point `P` such that `S_(1) P = 0.75 m` and `S_(2) p = 3 m` . How are the phases arriving at `P` related? What is the intensity at `P` when both `S_(1)` and `S_(2)` are on ? Speed of sound in air is `330 m//s`.
