Ray Diagram for a Convex Mirror

What happens with a convex mirror?

As the ray diagram shows, the image for a convex mirror is virtual, and upright compared to the object. A convex mirror is the kind of mirror used for security in stores, and is also the kind of mirror used on the passenger side of many cars ("Objects in mirror are closer than they appear."). A convex mirror will reflect a set of parallel rays in all directions; conversely, it will also take light from all directions and reflect it in one direction, which is exactly how it's used in stores and cars.

Moving an object from infinity toward a convex mirror gives an image that moves from the focal point toward the mirror, growing from a point to almost as large as the object. The image is virtual, upright, and smaller than the object.
