(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The light incident on a 45 degree prism undergoes total internal relfection at point P. What can you conclude about the index of refraction in the prism? (Determine either a minimum or maximum)

This is a right triangle, with the two other angles being 45 degrees and point is half on the hypotenuse.

3. The attempt at a solution

The answer in the back of the book is 1.41. I have no idea how they came up with this. Could someone explain about they found this number.
