What is the angle in degrees between the red and blue light


A hydrogen discharge lamp emits light with two prominent wavelengths: 656 nm (red) and 486 nm(blue). The light enters a flint-glass prism perpendicular to one face and then refracts through the hypotenuse back into the air. The angle between these two faces is 32 °.

Index of Refraction:

red: 1.572

blue: 1.587

What is the angle (in degrees) between the red and blue light as it leaves the prism?
