White light is spread out into its spectral components by a diffraction grating
White light is spread out into its spectral components by a diffraction grating. If the grating has 2000 lines per centimeter, at what angle does red light of wavelength 640 nm appear in first-order spectrum? (Assume that the light is incident normally on the grating.) Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer makes an angle of 43.4° with the axis of the polarizer. (a) What fraction of the original unpolarized light is transmitted through the analyzer?...
