White light is spread out into its spectral components by a diffraction grating. If the grating has 2 0 7.727 grooves per centimeter, at what angle does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.) How does the equation for the maxima of a diffraction grating compare to the equation for the maxima of a double slit?
