      Lenses and Image Formation 1 Introduction When light travels from one medium to another, part of the light can be transmitted across the media surface and refracted as shown in Figure 1. • Refraction means that the light beam bends. • This bending takes place because the light beam’s (i.e., photon’s) velocity changes as

      Lenses and Mirrors 2 For a spherical lens, parallel light incoming to a lens with convex surfaces will converge on its focal point, while parallel light incident on a concave lens will diverge away from its focal point (Figure 3). The image location for either mirrors or lenses can be found by a ray diagram. A ray diagram is
