The angles of incidence and refraction of a monochromatic ray of light of wavelength lamda at an air-glass interface are i and r, respectively. A parallel beam of light with a small spread delta lamda in wavelength about a mean wavelength lamda is refracted at the same air-glass interface. The refractive index mu of glass depends on the wavelength lamda as mu(lamda) = a + b//lamda2 where a and b are constants. Then the angular spread in the angle of refraction of the beam is
