Q.16 Boojho stands at A just on the side of a plane mirror as shown in Fig. Can he see himself in the mirror? Also can he see the image of objects situated at P, Q and R?

No, Boojho can’t see himself in the mirror. As the reflected ray of his image formed behind the mirror won't reach his eyes, so he won't be able to see himself in the mirror.

He can see the image of the object at P and Q because the reflected ray of their image can reach his eyes while he cannot see the image of the object at R as the reflected ray of the image at R cannot reach his eyes.
