Application for total Internal Reflection (Eugene and Imran)

diamond animation (3k)      

1. The cut of the diamond favors total internal reflection. Most rays entering the top of the diamond will internally reflect until they reach the top face of the diamond where they exit. This gives diamonds their bright sparkle. Notice in this animation that a ray entering the top doesn't exit the diamond until it reaches the top surface.

2. Prismatic binoculars use the principle of total internal reflections to get a very clear image
