In YDSE, the slits have different widths. As a result, amplitude of waves from slits are A and 2A respectively. If `I_(0)` be the maximum intensity of the intensity of the interference pattern then the intensity of the pattern at a point where the phase difference between waves is `phi` is given by `(I_(0))/(P)(5+4cos phi)` . Where P is in in integer. Find the value of P ?
