Section V-2a: Index of refraction n of a glass plate In this section you will illuminate a glass plate of thickness d and index of refraction n using a He-Ne laser beam. The beam is incident on the face of the plate that is covered with a wet paper as shown in fig. a. What is observed on the wet paper is shown in fig. b. Fig.a Fig.b The picture is a dark circle of d p radius R on a red background. The index of refraction n of e plate is given by the Incident laser beam the plate is given by the equation: 2 R 2 2 4 1 R d n + = Glass plate Wet paper (page 2)
