Snells Law and a triangle prism

  1. Jul 13, 2011 #1
    A light ray in air strikes the flat side of a right angle prism at a right angle. The prism has 32 58 as the other angles with 32 degrees being in the bottom and the right angle being to the right of it. The light ray consist of two different wavelenghts. When it emerges at the face AB. It was been split into two different rays that diverge from each other at 8.5 degrees. The first ray is 12 degrees lower then when the initial ray strikes the prism

    Find the index of refraction of the prism for each of the two wavelenghts?

    nsintheta=nsintheta


    since air is 1 is it just

    sin70/sin 58

    and

    sin78.5/sin58

    A diagram would be nice.
