Question

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?

Answer 1

Boojho can see image of an object if the reflected ray can reach his eyes. Reflected rays from P and Q can reach the eyes of Boojho, hence he can see P and Q. Reflected rays from A move away from him and never reach his eyes. Hence, he cannot see his own image. Reflected rays from R pass from under his eyes and hence he is unable to see R too.
