Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
