Trace the path of a ray emitted from the tip of the object through the focal point of the mirror and then the reflected ray that results. start by extending the existing ray emitted from the tip of the object. then create the reflected ray. draw the vector for the reflected ray starting from the point where the incident focal ray hits the mirror. the location and orientation of the vector will be graded. the length of the vector will not be graded.
