When light is incident on a glass-air interface some light refracts (bends),according to the Snell's law,while some light is reflected back to glass. When the angle of incidence exceeds a certain value,called critical angle,all the light is reflected creating the effect called total internal reflection. Here a right angle glass prism is used to demonstrate the phenomenon. In this photograph all light is reflected at the prism's hypotenuse. Photo 2 of 2 | |
