PLANE MIRRORSA plane mirror is a planar reflecting surface, on which specular (regular) reflection is observed.
A virtual image is formed by a plane mirror. The rays reflecting from the mirror appear to have originated from the location of the virtual image.
On a diagram, a virtual image is usually depicted by a broken (dotted) arrow.
The image in a plane mirror is located as far behind the mirror as the object forming it is in front of the mirror. It is the same size as the object. (magnification = +1)

A ray diagram is used to trace the path of light rays.
