How will you explain the statement 'we cannot see the objects in a dark room'?

उत्तर
Light enables us to see objects around us. We see an object when light falls on it and gets reflected from its surface and enters our eyes. In a dark room, there is no source of light. Thus, no light falls on the surface of objects, and hence we do not see them. This is why we cannot see the objects in a dark room.
