It can be seen that the image is virtual, upright, and diminished.

 Image formation by a convex mirror.

The focal length  of a convex mirror is redefined to be minus the distance between points  and . In other words, the focal length of a concave mirror, with a real focus, is always positive, and the focal length of a convex mirror, with a virtual focus, is always negative. Table 6 shows how the location and character of the image formed in a convex spherical mirror depend on the location of the object, (with ).
