An Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material.

ends on the angle of incidence when a ray of light enters the Perspex block.Scientific Background: -Refraction occurs when the speed changes when the lights travels from one medium to another medium. ... light is refracted, an increase in the angle of incidence, I, produces an increase in the angle of refraction, r. The scientist, Willebrord Snell discovered the link between the two angles where thei ...
