CAIE IGCSE Physics EXTENDED 3.2.2.9 Use of optical fibres, particularly in
Practise explaining how optical fibres guide light and why total internal reflection supports telecommunications signals.
How this is tested
- explain signal transmission in an optical fibre using repeated total internal reflection
- link fibre use in telecommunications to guided light travelling along a narrow core
