Optical Fibres A Level Physics

This video explains how optical fibres (or optical fibers if you're American) work for A Level Physics. • Optical fibres use total internal reflection in order to send information. A light signal is sent down an optical fibre which can be received quite a distance away. The signal isn't perfect because different light rays travel different distances - this is called modal dispersion. The signal is put through a filter in order to get the original signal back out. • Thanks for watching, • Lewis • This video is recommended for anyone studying A Level Physics in the following exam boards: • AQA • CIE • Edexcel (don't need to know details) • Edexcel IAL • Eduqas • IB • OCR A • OCR B • WJEC • _____________________________________ • MY PHYSICS WEBSITES • Find even more videos organised by exam board and topic at: • GCSE Physics Online • ► https://www.gcsephysicsonline.com • A Level Physics Online • ► https://www.alevelphysicsonline.com • MY YOUTUBE CHANNEL • Your support in watching this video has been invaluable!
