I Experiment EQUIPMENT NEEDED: -Optics Bench -Ray Plate and Base -Slit Plate -Cylindrical Lens -Viewing Screen. Introduction Introductory Optics System Dispersion and Total Internal Reflection ] -Light Source -Component Holder -Slit Mask -Ray Table Component Holder Angle of Incidence Figure 6.1 Equipment Setup In this experiment you will look at two phenomena related to refraction: Dispersion and Total Internal Reflection. Dispersion introduces a complication to the Law of Refraction, which is that most materials have different indexes of refraction for different colors of light. In Total Internal Reflection, it is found that in certain circumstances, light striking an interface between two trans- parent media can not pass through the interface. Procedure Set up the equipment as shown in Figure 6.1, so a single light ray is incident on the curved surface of the Cylindrical Lens. Dispersion Set the Ray Table so the angle of incidence of the ray striking the flat surface of the lens (from inside the lens) is zero-degrees. Adjust the Ray Table Component Holder so the refracted ray is
