a reflected optical image (as seen in a plane mirror)

It is an image that is upright and appears on the opposite side of the mirror from the source object. Rays from the object that are reflected by the mirror appear to come from the virtual image, although they never enter that space. The image you see in a plane mirror is a virtual image, but there are others, such as the image formed by a convex "wide angle" mirror
