The image we see in plane mirror is

The image formed by a plane mirror is characterized by several distinct properties. First, it is a virtual image, meaning the light rays do not actually converge at the image position but only appear to originate from behind the mirror [1]. Consequently, a virtual image cannot be projected onto a screen [1]. Second, the image is the same size as the object and is located at the same distance behind the mirror as the object is in front of it [1]. Third, the image is laterally inverted, a phenomenon where the left side of the object appears as the right side of the image and vice versa [3]. While virtual images cannot be caught on a screen, they can be photographed because the camera lens converges the diverging rays to form a real image on the film or sensor. Therefore, option 3 is the most accurate description.
