Can he see himself in the mirror? Also, can he see the image of objects situated at P, Q and R?
Solution and Explanation
Boojho can't see his own image because he is not standing in front of the mirror. However, he is able to see objects at P and Q because the rays coming from P and Q get reflected by the mirror and reach his eyes. The ray from object R does not reflect and reaches Boojho, so, he cannot see object R.

Concepts Used:
Reflection of Light
When a light ray falls on any object, it is bounced back from the object. This process is known as the Reflection of light. The light reflected from the object falls into our eyes, making the object visible to us. All the things we see around us are because of reflection.
The reflection of light depends on the type of object. A polished or smooth surface reflects most of the light falling on it, while a rough surface absorbs some amount of light and reflects back the rest of the light. The direction of reflected rays depends upon the surface of the object.
