Sound from two identical sources `S_(1)` and `S_(2)` reaches 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)` :-

A

`l_("max") =0.64l_0`

B

`l_("min")=0.36 l_0`

C

`I_("max")//I_("min")=16`

D

`I_("max")//I_("min")=1.64//0.36`
