Diverging mirrors, sometimes refered to as "shoplifting mirrors," only form reduced, virtual images. As can be seen in this diagram below, the incident rays (yellow) all begin on the top of the object (red arrow) and are each scattered from the mirror's front, convex surface. The reflections when dotted back (green lines) form a virtual image (gray arrow) behind the mirror.

As with the diagrams for converging mirrors, we will be using a vertical line to represent these convex mirrors so as to minimize any spherical aberrations.
