Section V-2a:Index of refraction nof a glass plateIn this section you will illuminate a glass plate of thickness dand index of refraction nusing 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.2RdIncident laser beamGlass plateWet paperFig.aFig.bThe picture is a dark circle of radius Ron a red background. The index of refraction nof the plate is given by the equation:2241Rdn+=(page 2)
