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 700 lines per mm, projecting a pattern on a screen 2.9 m behind the grating. Part A How wide is the spectrum that corresponds to m = 1? Express your answer with the appropriate units. W₁ = .52 μÅ m www Submit Previous Answers Request Answer ?
