Modified from College Physics , 7 th Ed., Serway, Faughn, and Vuille. For the quizzes and tests, you should know all the concepts and equations in this summary. Section 23.1: Flat Mirrors Images are formed where rays of light intersect or where they appear to originate. A real image is formed when light intersects, or passes through, an image point. In a virtual image the light doesn't pass through the image point, but appears to diverge from it. The image formed by a flat mirror has the following properties: 1.
