Transcript

A plane mirror forms a virtual image behind the mirror, at the same distance at which the object is placed in front of the mirror. So, A will form image A’ P will form image P’ , Q will form image Q’ and R will form image R’ Since mirror is not between A and A’, ∴ Boojho at A cannot see his reflection. Similarly, Since mirror is not between R and R’, ∴ Boojho at A cannot see reflection of point R. But he can see images of point P and Q
