Example $2$

Shown below is the central portion of a pattern formed by a two$-$slit diffraction experiment. The bright spots are equally spaced $($except for the missing spots$)$ at $1\mathrm{.}53$ mm center$-$to$-$center on a screen $2\mathrm{.}50$ m away. The light source was a helium$-$neon laser with wavelength $632\mathrm{.}8$ nm $.$ Determine the width of the slits and the distance between them.

Can the steps to solve the problem be written out step by step
