WebSep 12, 2024 · For a spherical mirror, the optical axis passes through the mirror’s center of curvature and the mirror’s vertex, as shown in Figure 2.3. 1. Figure 2.3. 1. A spherical mirror is formed by cutting out a piece of a sphere and silvering either the inside or outside surface. WebMar 5, 2024 · The calculation goes as follows (Equation ): Notice that the light is diverging by the time that it reaches the second face. The light is still diverging, so the image is virtual. The distance of the image from the second face is 1.42 ÷ 0.007 246 = 196 cm, and it is to the left of the second face. The magnification of a thick lens is easily found.
