Derivation of acceptance angle

Webinterface at an angle greater than the critical angle, the light is totally reflected back into the denser medium. This is called total internal reflection. The critical angle is the angle of incidence for which the angle of refraction is 90˚. The critical angle for glass to air is 41.3˚, and for glass to water it is 61.7˚.
