A highly collimated $($parallel$)$ beam of electrons is shot through a single slit of width $17\mathrm{.}7$$17\mathrm{.}7$m$.$ The electrons are moving with a speed of $8\mathrm{.}728\mathrm{.}72$km$/$s$.$ When they hit the screen, located at distance $1\mathrm{.}651\mathrm{.}65$m away, the distribution of hitting positions makes an interference pattern with a central peak and minima on either side.

This pattern will be identical to the pattern produced by light of what wavelength?
