Figure 2: A prism pair. [lira'ar a ray trace for the red and blue rays for the pair of prisms shown in Figure 2 until the rays exit the second prism. The prisms are in air. The refractive index for glass for the red and blue rays are given below. The rays enter the glass at an angle of ll degrees. The prisms are equilateral triangles with angle faces degrees with respect to each ether. Label the internal and external angles of the rage at each interface. To get full credit for this problem. careilly label all angles on the diagram and show your work a nonquantitative sketch is insufcient
