The indices of refraction for violet light (? = 400 nm) and red light (? = 700 nm) in diamond are 2.46 and 2.41, respectively. A ray of light traveling through air strikes the diamond surface at an angle of 53.5? to the normal. Calculate the angular separation between these two colors of light in the refracted ray.
