Caption

Fibre optics. Fingers weave through optical fibres which are conducting white light. The fibres are made from flexible glass which has a high refractive index. Each fibre is then coated with a protective outer layer having a low refractive index. The light beams emerging from the end of each fibre have been completely internally reflected. The light may thus travel along the entire cable with little or no absorption. Bundles of optical fibres may be used to carry images, or high volumes of data such as telephone conversations.
