Refraction of Light
When light is transmitted from one medium to another, as in Fig. 3. 1, it usually changes its direction (unless its angle of incidence is 90 degrees). If it travels slower in the second medium, as in Fig. 3. 1, it is bent toward the normal; if it travels faster, it is bent away from the normal.
