Single slit

Light from a red laser, with a wavelength of $650$ nm $,$ shines on a single slit. The picture below shows the intensity of the light as a function of position on a screen some distance from the single slit. The center of the pattern corresponds to $x=0$ cm $,$ and you can assume the first minimum in the diffraction pattern corresponds to exactly $x=8\mathrm{.}00cm.$
