Optical Fibre
A solid, thin transparent rod made of glass which light can travel in by total internal reflection, coated by material of lower refractive index so light doesn't escape from it if it touches another fibre

-
Laws
Law 1: The incident ray, the refracted ray and the normal at the point of incidence all lie in the same plane
-
Experiments
Verifying Snell's Law
Laser, glass block, laser adjusted hitting NatPoI at different angles (diff values of i and r) - should be similar to prove they're constant
