Table 5.1 Data Ray incident on: Flat Surface Curved Surface A tight? o' Incidence Refraction Incidence Refraction l I z a Now let the incident ray strike the curved surface of the lens. [Just rotate the Ray Table 180\".) The internal angle of inddence for the at surface of the Cylindrical Lens is shown in Figure 5.2. Set this angle of incidence to the values you have already listed in the table (Incidence). Record the corresponding angles of refraction {Refractionz} 3' Using your collected values for Incidence1 and Refraction], determine the index of refraction for the acrylic from which the Cylindrical Lens is made. [As in experiment 1, assume that the index of refraction for air is equal to 1.0.) n : l. 3' Using your collected values for Incidence2 and Refraction2 redeterroine the index of refraction for the acrylic from which the Illlylindiical2 Lens 15 made. D2: 3 Is the Law of Refraction the same for light rays going in either direction between the two media
