1.	Enter into a dark room from a very bright place.What happens? Sit in a dark room for sometime. Then go into a bright light room. What happens?
Answer» If we enter into a dark room from a very bright place first we cannot see anything in the room. Because the pupil is very small in size and very less amount of light enters into the eyes. As the time progresses the pupil becomes large in size and we will be able to see things properly. If we go into a bright light room from a dark room, at first we cannot see anything in light from because the pupil does not bear the intensity of light. The pupil gradually lessens its size and we are able to see things properly.
