Question

Two speakers separeted by some distance emit sound of the same frequency. At some point P the intensity due to each speaker separately is I_(o). The path difference from P to one of the speakers is (1)/(2) lambda greater than that from P to the other speaker. What is the intensity at P if (a) the speakers are coherent and in phase, (b) the speakers are incoherent, and (c ) the speakers are coherent but have a phase different of 180^(@)?
