A hydrogen discharge lamp emits light with two prominent wavelengths: 486 nm (blue) and 656 nm (red). The light enters a flint-glass prism perpendicular to one face and then refracts during the hypotenuse back into the air. The angle among these two faces is 31degrees.
Index of refraction for red is 1.572
Index of refraction for blue is 1.587
What is the angle (in degrees) among the red and blue light as it leaves the prism?
