Two thin parallel slits that are $0\mathrm{.}0131$ mm apart are illuminated by a laser beam of wavelength $586$ nm$.$ On a very large distant screen, what is the total number of bright fringes $($those indicating complete constructive interference$),$ including the central fringe and those on both sides of it$?$ Solve this problem without calculating all the angles! $($Hint: What is the largest that sincan be$?$ What does this tell you is the largest value of m$?)$
