Reflection & Refraction
PHY 201 & 231
Loyd #40 pre-lab applies. In this experiment, the 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. The students will discover also that the angle of incidence is equal to the angle of refraction for a reflection from a plane surface and that a light ray traveling in air will be refracted once transmitted into a prism.
