Sounds from two identical sources S_(1) and S_(2) reach a point P . When the sounds reach directly, and in the same phase, the intensity at P is I_(0) . The power of S_(1) is now reduced by 64% and the phase difference between S_(1) and S_(2) is varied continuously. The maximum and minimum intensities recorded at P are now I_("max") and I_("min")

Two identical sources of sound S_(1) and S_(2) produce intensity I_(0) at a point P equidistant from each source . (i) Determine the intensity of each at the point P . (ii) If the power of S_(1) is reduced to 64% and phase difference between the two sources is varied continuously , then determine the maximum and minimum intensities at the point P . (iii) If the power of S_(1) is reduced by 64% , then determine the maximum and minimum intensities at the point P .

Two sources of sound S_1 and S_2 vibrate at same frequency and are in phase. The intensity of sound detected at a point P as shown in the figure is I_0 . (a) If theta equals 45^@ , what will be the intensity of sound detected at this point if one of the sources is switched off ? (b) What will be the answer of the previous part if theta= 60^@ ?
