10.1 Ray Optics: Reflection and Refraction
... Figure 10.12 shows light from an object striking a mirror and reflecting through the focal point of the mirror. The reflected rays form an image of the object. This is called a real image, because light rays converge to pass through the image. You can see a real image if you place a small screen or ...
