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 500 lines per mm, projecting a pattern on a screen 1.9 m behind the grating. Part A How wide is the spectrum that corresponds to m = 1? Express your answer with the appropriate units. W₁ = .49 Submit Part B. m Previnue Aneware Remiect Answer How much distance separates the end of the m= 1 spectrum and the start of the m = 2 spectrum? Express your answer with the appropriate units. Ayzi = Value Units
