Abeam of light of two different wavelengths enters a pane of glass 3.2 mm thick at an angle of incidence of 59°. the indices of refraction for the two different colors are 1.5 and 1.53. because of dispersion, the colored beams, although parallel, are separated by a small distance. how far apart are they? (give your answer to the nearest 0.0001 mm)
