A kind of glass has an index of refraction of 1.640 for blue light of wavelength 430 nm and an index of 1.595 for red light of wavelength 670 nm. If a beam containing these two colors is incident at an angle of 30.0° on a piece of this glass, what is the angle between the two beams inside the glass?
