Can plane mirror form real image?

A virtual image is one that can be seen, and a real image can be projected. Although we usually use plane mirrors for the purpose of producting virtual images, that is being able to see an object in the mirror. It possible for a plane mirror to produce a real image in conjuction with another mirror. In order for a real image to be produced the mirror must bend the incident light rays in such a way that they converge to a single point. According to the law of reflection the angle of incidence of an incident ray equals the angle of reflection of a reflected ray, so parallel light rays are reflected back at the same angle producing a virtual image of a real object.

In order for a plane mirror to produce a real image ir must be reflecting the virtual image produced by another mirror or a lens. In this context we call the virtual image a virtual object. If the light rays coming from the virtual object converge at a point behind the plane mirror the reflected rays will converge in front of the mirror, forming a real image.
