Q1. A certain kind of glass has an index of refraction of 1.660 for blue light of wavelength 420 nm and an index of 1.615 for red light of wavelength 680 nm. If a beam containing these two colours 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?
