Answer 2

Answer:

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. ... If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image.
