Description of virtual image that forms behind mirror.
Do ray tracing of object with dimension traveling to the eye from the mirror and the virtual image that forms
Do another ray tracing of multiple rays emanating from an object to the mirror and show the virtual image as convergence of reflected rays.
Define magnification as ratio image size to object size as well as ratio of image distance to object distance.
