The image formed by a plane mirror is ____.

The correct answer is: All of the above

• A plane mirror is a mirror with a flat reflective surface. If a ray hits a plane mirror, the angle of reflection is equal to the angle of incidence.
• The image produced by a plane mirror is always virtual (that is, the light rays do not actually come out of the image), upright, and the same shape and size as the object it reflects.
• The image and object are equidistant from the plane mirror, the image size is equal to the object size, and the image is upright.
• However, the image is a flipped "mirror image" of the object.
