Part A

A physics instructor wants to project a spectrum of visible$-$light colors from $400$ nm to $700$ nm as part of a classroom demonstration. She shines a beam of white light through a diffraction grating that has $600$ lines per mm$,$ projecting a pattern on a screen $2\mathrm{.}4$ m behind the grating.

How wide is the spectrum that corresponds to $\backslash ($ m$=1\backslash )?$
