उत्तर
The reflection takes place at the surface of the plane mirror in accordance with the laws of reflection in which the angle of incidence is equal to the angle of reflection.
The light coming from the letter p is reflected from the surface of the plane mirror. When these reflected rays are produced backward, they form an inverted virtual image of letter p which is the same in size of letter p.
