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 .

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")

There are 10 sound sources each producing intensity I at a point independently. The are incoherent. Average intensity of sound at that point will be:

The two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 50% by reducing its width then the intensity of light at the same point will be
