Expand description

Define the parameters required to solve a refraction problem.

In the following drawing, we want to find x when we know w, h, d, and the ratio of refractive indices n where n = n2/n1.

a and b are angles, n1 and n2 are refractive indices, d, h and w are lengths.

                      ----/                            |
                 ----/                                 |
          x   --/                    d-x               |
