Ray Diagrams Power Point this is a powerpoint made the famous physicist Dave Lock. I hope it works.This link will likely download a .ppt file. If you don’t have Powerpoint on your computer, try opening it with Google Slides. If that doesn’t work, try watching more (all) of Doc Physics on YouTube. He does some great ray optics diagrams like this one:

Optics PreTest Key

ROPA (Ray Optics Problem Assignment) Key

Index of Refraction and Snell’s Law Questions KEY


How Snell’s law can be derived using some simple geometry and a marching band. Remember the marching band? Check out this video form Doc Physics:

From Last  Year (but still neat!):

Did you know that the United Nations has declared 2015 the International Year of Light, to showcase “to the citizens of the world the importance of light and optical technologies in their lives, for their futures, and for the development of society.” Cool eh?

To kick off the festivities, the Perimeter Institute (Pi) of Theoretical Physics, one of my favourite places (out in Waterloo Ontario), made these neat photos with 20 facts about light. Some you will know, but they are cool anyways. Check ’em out, and show them to your parents.
