Mirror Image

Suppose someone stands in front of a plane mirror. If he lifts his left hand, the image in the mirror shows his right hand and vice-versa. The left half of a body becomes right half of its mirror image and right half becomes left half.                                                                             

Note: If not mentioned, the mirror is assumed to be placed to vertically right of the object.
