Total internal reflection is an optical phenomenon that occurs when a ray of light strikes a medium boundary at an angle larger than the critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary no light can pass through, so effectively all of the light is reflected. The critical angle is the angle of incidence above which the total internal reflection occurs.
You can browse Wikiversity by resource type. This route is rather rough and ready for the time being, as people's consistency and willingness to categorise their resources by type has been somewhat lacking. It is hoped that by spotlighting the "by resource type" exploration path, people will slowly improve the tagging of resources by resource type. {{#categorytree:Resources by type|mode=all|depth=10|hideroot}}
