How can I calculate the phase difference, in radians, between the rays from the two slits as they strike the screen at the specified distance from the central maximum, given an electromagnetic radiation of intensity I0 = 340 W/m2 that passes through two parallel narrow slits that are d = 1.4 μm apart and strikes a screen located L = 2.2 m from the slits. The intensity of the radiation on the screen at y = 3.9 mm from the central interference maximum is I = 95 W/m2. I know the equation is 2 acos (I/I0)1/2 but can't figure out the answer
