The light rays transmit telephone, radio, and television signals. Fibre optics is also used in medicine to allow scopes to see inside organs, blood vessels, etc. in minute detail. Lenses. Refraction is why lenses work. The physics is nearly identical to that of the spherical mirrors we recently looked at. Drawing ray diagrams are ALMOST the same ................
