Frequently Asked Questions & Expert Answers on Cassini Spherical Primary Mirror from OpticsPlanet. Answer. Answer: Usually convex mirror or plane mirror forms virtual images.But it can form a real image, if the object is virtual, i.e., if the light rays converging at a point behind a plane mirror (or a convex mirror) are reflected to a point on a screen placed in front of the mirror, then a real image will be formed. ...
