The index of refraction for a certain type of glass is 1.637 for blue light and 1.607 for red light. When a beam of white light (one that contains all colors) enters from air a plate of this glass at an incidence angle of 38.050, what is the absolute value of θ, the angle in the glass between blue and red parts of the refracted beams?
