Ray Diagrams for Concave Mirrors
Object Located At the Center of Curvature: Ray diagrams are meaningful tools for denoting the location of an image as generates through a concave mirror. To denote the location of an image by using a ray diagram, at least two sets of incident and reflected rays must be constructed for strategic positions on the object. The image of an object is the location whereas light rays from that object intersect upon reflecting from a mirror. Through constructing at least two sets of incident and reflected rays, this image location can simply be found.
