A beam of light with red and blue components of wavelengths 670 nm and 425 nm, respectively, strikes a slab of fused quartz at an incident angle of 37°. On refraction, the different components are separated by an angle of 0.00128 rad. If the index of refraction of the red light is 1.4987, what is the index of refraction of the blue light?
