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. 2 R d Incident laser beam Glass plate Wet paper Fig.a Fig.b The picture is a dark circle of radius R on a red background. The index of refraction n of the plate is given by the equation: 2 2 4 1 R d n + = (page 2)
