$[-/4$ Points$]$

SERPSE$1036\mathrm{.}2.$P$\mathrm{.}007.$

A student holds a laser that emits light of wavelength $636\mathrm{.}4$ nm $.$ The laser beam passes though a pair of slits separated by $0\mathrm{.}500$ mm $,$ in a glass plate attached to the front of the laser. The beam then falls perpendicularly on a screen, creating an interference pattern on it$.$ The student begins to walk directly toward the screen at $3\mathrm{.}00\frac{m}{s}.$ The central maximum on the screen is stationary. Find the speed of the $50$th$-$order maxima on the screen.
