The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660. A beam of white light in this glass strikes the glass-air interface at a 21.10 degree angle of incidence and refracts out into air. Find the angular separation between the red and violet components of the spectrum that emerges from the glass?
