Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into ...
In 1943, the two German scientists Goos and Hänchen performed an experiment showing that in total internal reflection ... a non-local response on the optical reflection from gold.
Mark explains, using an animation, how optical fibres are able to transmit light over great distances, and demonstrates how total internal reflection can bend light around a corner. Students can ...
