  • Optical fibres – development and uses
  • Duration: 05:11
  • Mark Miodownik describes how optical fibres were developed in medicine and dentistry in order to transmit light into the body, and with the goal of being able to transmit an image from within the body to the surgeons operating from the outside. He explains, using an animation, how optical fibres are able to bend and transmit light for great distances. Using a laser demonstration and a bent jet of water, Mark demonstrates and explains total internal reflection. Fibre optic communications now transmit a massive quantity of information in many contexts around the world. First broadcast in the Learning Zone on BBC2 in May 2012 as part of the programme Materials: How They Work.
