Klaynos Posted February 26, 2006 Share Posted February 26, 2006 It occures when you have two different materials with differnt refractive indexes (n). The light moving from the higher n to the lower n (say from glass to air) if it at or below a certain angle will get refected back into the glass with no rays passing out into the air. It can be seen to occure with a stream of water and a laser pen. But the most common example is fiber optic cables. http://en.wikipedia.org/wiki/Total_Internal_Reflection is probably worth a read as well as http://en.wikipedia.org/wiki/Fiber_optics Link to comment Share on other sites More sharing options...
