In the arrangement shown in figure, light of wavelength `6000 Å` is incident on slits `S_(1)` and  `S_(2)` have been opened such that `S_(3)` is the position of first maximum above the central maximum and `S_(4)` is the closest position where intensity is same as that of the ligth used, below the central maximum Point O is equidistant from `S_(1)` and `S_(2)` and O' is equidistant from `S_(3)` and `S_(4)`. Then intensity of inciden light is `I_(0)`
