Problem: White light is spread out into its spectral components by a diffraction grating. If the grating has 1,950 grooves per centimeter,
Part A: At what angle does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.)
Please show me step by step or type in formulas used. I am so lost!! Thanks.
