White light enters flint glass from air (n₁ = 1). The angle of incidence is 8, = 63 degrees. Due to dispersion in the glass, the index of refraction for red light is 1.662, while the index for violet light is 1.698. Due to this difference, the violet and red parts of white light are refracted by different amounts. What is the difference in refraction angle (AO) between violet and red fin this situation?
