A beam of white light is incident on a slab of dense flint glass at an angle of incidence of 60°. Flint glass, as with most materials, displays a dispersion where the refractive index is a function of the wavelength of incident light. We can often write this dispersion using the Cauchy relation n(2)=A+BA-2). For the case of Flint glass, A = 1.728, and B = 0.01342 µm2. What is the difference in angle of the refracted beam between blue light of wavelength 400 nm, and red light of wavelength 700 nm?
