Two slits spaced $0\mathrm{.}0720$ mm apart are $0\mathrm{.}800$ m from a screen. Coherent light of wavelength $$ passes through the two slits. In their interference pattern on the screen, the distance from the center of the central maximum to the first minimum is $3\mathrm{.}00$ mm $.$ The intensity at the peak of the central maximum is $0\mathrm{.}1000\frac{W}{m^2}.$

Part A
