Question Question 1
Suppose you are in a dark room. Can you see objects in the room? Can you see objects outside the room? Explain.
No, we cannot see objects in a dark room because there is no light to illuminate the objects in the room. When light falls on the eyes after reflecting from the object, it becomes visible. If the light is available outside the room, then the objects present would reflect it and hence we would be able to see objects.
