White light spans the wavelength range be$-$ tween about $400$ nm and $700$ nm$.$

If white light passes through two slits $0\mathrm{.}579$ mm apart and falls on a screen $2\mathrm{.}2$ m from the slits, what is the distance between the first$-$order violet and the first$-$order red fringes?

Answer in units of mm$.$
