What kind of mirror is required for obtaining a virtual image of the same size as the object?
A plane mirror is required in order to obtain a virtual image of the same size as the object.
Explanation with the image is posted for reference only.
The image formed by a plane mirror is always virtual, which can never be captured or obtained on a screen, and appears to be on the opposite side as that of the mirror.
The virtual images form when the light rays appear to meet at a definite point, after reflection from the mirror.
It is used in kaleidoscopes, shaving mirrors, dentists' mirror, torch lights, etc.
Characteristics of the image formed by a plane mirror are virtual, erect (upright), of the same size, at the same distance and laterally inverted.
