            The reflected rays PR and QS diverge from each other, therefore, 
  they are extended backwards to meet at I, the image I is therefore the virtual 
  image behind the mirror. From the geometry of the ray diagram, it is obvious 
  that v = u. The image of a finite sized object in a plane mirror is virtual, 
  erect, laterally inverted, behind the mirror and at same distance as the object. 
  These are obvious consequences of the laws of reflection; these characteristics 
  of the image are illustrated in Fig. 3
