o air or the reverse, the rays are bent at the surfaceseparating the media. The bending of the rays of light iscalled refraction. . We can show the refraction of light rays when light passesfrom air into water by the experiment illustrated in Fig. 182.A beam of light AB is allowed to pass through a… … FIG. 182. — The beam of light is bent in passing from air into water. NN drawn perpendicular to the surface of the water at thepoint the light enters. When light passes from water to air, the rays are bent in theopposite direction, that is, away from the line drawn perpen-dicular to the surface at…
