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 dif- fraction grating that has 500 lines per mm, projecting a pattern on a screen 2.4 m behind the grating.

a. How wide is the spectrum that corresponds to m = l?

b. How much distance separates the end of the m = 1 spectrum
