3D Refraction Simulator

The 3D Refraction Simulator provides a complete workspace for investigating the refraction and reflection of light at a boundary.  The simulation allows you modify the angles of incidence and the indices of refraction of two medium and observe the effect on the brightness and angles of the reflected and refracted rays.

Instructors may also be interested in viewing the accompanying Notes page. Technical information, teaching suggestions, related resources that complement this Interactive, and ideas for incorporating the lesson into a unit on Refraction and Lenses are provided on the Notes page. View Notes.

We owe a special thanks to Physics teacher Martin Kirby for donating the 3D Refraction Simulator to our Interactives collection. If you like this sim, you can tap on the Donate button and buy him a cup of coffee (or a pot of coffee); he'd appreciate it. Martin has contributed many other simulations to our Interactives collection. You can view them all by visiting our page listing all Martin Kirby Simulations. Or visit Martin's website (kirbyx.com) to learn more.
