Suppose you are inside the water in a swimming pool near an edge. A friend is standing on the edge. Do you find your friend taller or shorter than his usual height? Why?


#2

When I saw my friend through water, he seems tube taller than his actual height. This is due to the light rays bends away from the normal as they enters rarer medium (air) from denser medium (water).
