Object Located Between the Focal Point and the Mirror
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 should be constructed for strategic positions on the object. The image of an object is the location while light rays from in which object intersect upon reflecting from a mirror. Through constructing at least two sets of incident and reflected rays and this image location can simply be found.
