An image can be both real and virtual. When light rays intersect after reflection, a
true image is formed. When the light rays after reflection do not actually intersect
but appear to diverge from it, a virtual image is formed (these rays of light intersect
when produced backwards).
Ray Diagrams of Plane Mirrors:
When drawing ray diagrams, the following rays are usually taken into account: A
ray of light incident at 90 degrees on a plane mirror is reflected from the mirror
along the same path. A ray of light falling at any angle on a plane mirror is
reflected from it in such a way that the angle of incidence equals the angle of
reflection. The image is formed when the reflected rays appear to collide.
