Q.1 Suppose you are in a dark room. Can you see objects in the room? Can you see objects out¬side the room ?

If we are in a dark room, then it is not possible to see objects in the room. However, objects outside the room are visible to us.

An object becomes visible when the reflected light from the object reaches our eye. If there is no light in the room, then the objects inside the room cannot reflect any light.

Hence, we cannot see anything in a dark room. But if there is light outside the room, then we can see the objects outside the room.
