A diamond in air is illuminated with white light. On one particular facet, the angle of incidence is 26.00°. Inside the diamond, red light (λ = 660.0 nm in vacuum) is refracted at 10.48° with respect to the normal; blue light (λ = 470.0 nm in vacuum) is refracted at 10.33°.
(a) What are the indices of refraction for red and blue light in diamond?
(b) What is the ratio of the speed of red light to the speed of blue light in diamond?
(c) How would a diamond look if there were no dispersion?
