Suppose you are in a dark room. Can you see objects in the room? Can you see objects outside the room? Explain.                                                           

Answer:

We see only that objects from which reflected rays enter in our eyes. When we are in a dark room then we do not see objects. We can see objects outside the room because out of the room the light is available and that rays of light enter in our eyes after reflection.
