Light is completely internally reflected in several sorts of reflecting prism and in fibre optics, by which very long fibres of substantial-index glass clad with a thin layer of reduce index glass are assembled facet-by-side in exact order. The light admitted into one conclusion of every fibre is transmitted along it without decline by 1000s of successive internal reflections on the interlayer between the glass as well as cladding.
