A two$-$slit interference experiment uses laser light of wavelength $655$ nmnm$.$ The slits are $0\mathrm{.}230$ mmmm apart and $1\mathrm{.}75$ mm from the screen on which the interference pattern appears. The intensity of the light at the central bright fringe is I$0$I$0=0\mathrm{.}0520$ W$/$m$2$W$/$m$2.$ Find the intensity at a point on the screen $6\mathrm{.}50$ mmmm from the central bright fringe.
