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

PLANNING: - Title: - An Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different angles and how the displacement depends 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. If the light …

…and depths (D) to verify d "f D where i is constant, blocks of the same material but different D would be used. How is ƒÎ displacement d measured - use of a protractor and a sharp pencil. There were no anomalies in the graph. However, any anomalies that would have occurred would be due to inaccurate readings from measuring the lateral displacement with a ruler and the angle of refraction with a protractor.
