Answer 1

Answer:

(3) .. We see so many objects around us, colourful and different. On the way to school we see things like buses, cars, cycles, trees, animals and sometimes flowers. How do you think, we see all these objects?

Think of the same places at night time if it were completely dark. What will you see? Suppose you go inside a completely dark room. Are you able to see any objects in the room?

But, when you light a candle or a torch you can see the objects present in the room, isn’t it? Without light, things cannot be seen. Light helps us see objects.
