Reflection & Refraction

PHY 201 & 231

Lab PDF 1
Lab PDF 2

Loyd #40 pre-lab applies. In this experiment, students will measure the incident and refracted angles of a light ray through a prism. From these measurements, they will determine the index of refraction of the prism. Students will also discover that the angle of incidence is equal to the angle of reflection from a plane surface and that refraction can be eliminated at or above a critical incident angle if a light ray travels from a material with greater index of refraction to one with a lower index.
