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.

Leave a small stack of paper on each lab bench.
Leave the Laser Refraction Tank on the instructor's table after checking batteries and turning off. Make sure that the room has plenty of paper.
