An interference pattern is produced by light with a wavelength $540$ nmnm from a distant source incident on two identical parallel slits separated by a distance $($between centers$)$ of $0\mathrm{.}450$ mmmm $.$

Part A

If the slits are very narrow, what would be the angular position of the first$-$order, two$-$slit, interference maxima?
