Light impinges on a 1485 line per mm diffraction grating at an angle of incidence of 39.5 degrees. What wavelength, in nm, will be reflected in the first order at an angle of 14 degrees on the other side of the normal to the grating.
(c) At what angle would the second order light of the same wavelength be reflected on the same side of the normal to the grating as the incident of light?
