A light beam containing violet and red wavelengths is incident on a slab of quartz at an angle of incidence of 66.6 degree. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410nm (violet light). Calculate the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths. °
