Answer 2

Answer:

When you hold a mirror in front of you in a completely dark room, you will not see reflection of yourself in the mirror because light will not be there. We can see an object only when light rays emitted or reflected from the object reaches our eye. In a dark room, no light reaches our eye. Hence, no objects are visible. Outside the room, all objects are visible because light reflected from their surfaces reaches our eyes.
