Question

2. Is the candle visible through a bent pipe? If not, why?
3. What does this observation show?​

Answer 1

Answer:

2) No , we can't see the candle with a bent pipe because the light rays it emits would be stopped by the bent pipe so no rays will reach our eye to make the candle visible .

3) So the above observation shows that the light rays plays a very important role on making objects visible .
