The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Refraction & Total Internal Reflection

A beam of light from a helium-neon laser is directed at a tank of water and is refracted as it enters the water. The outgoing angle of refraction is smaller than the incident angle. Next, the laser is directed from below the water's surface. At a certain critical angle, the beam is totally reflected at the surface, there is no outgoing refracted beam.
