The indices of refraction for red, green, and violet light in glass are nred = 1.520, ngreen = 1.526, and nviolet = 1.538. When a ray of light passes through a transparent slab of glass, the emergent ray is parallel to the incident ray, but can be displaced relative to it unless the angle of incidence is zero. For light passing through a glass slab that is surrounded by air, which color is displaced the most?
