The angle of incidence when the angle of refraction is 90 o, and the ray changes from just refracting to total internal reflection, is called the critical angle. The diagram below shows the light ...

Just like ray diagrams showing reflection, all angles are measured from the normal – a line at 90° to the refracting surface. It is refraction that makes some objects appear to bend when they ...
