प्रश्न
In a completely dark room, if you hold up a mirror in front of you, will you see a reflection of yourself in the mirror?
उत्तर
An image is formed due to the reflection of light by a plane mirror. In a completely dark room, there is no light present in the room. Thus, no reflection of light takes place by the mirror placed in the room. Hence, no image will get formed by a mirror in a completely dark room.
