Question

You are standing at the edge of a pool looking down at an angle phi. Phi is the angle that would let you see the bottom corner of the pool IF there were no water in the pool. But if the pool is full of water (n=1.33) you aren’t looking at the corner. What spot are you seeing? Express your answer as a distance away from the corner and say whether it is along the bottom or along the far wall.  The depth d and height h are both 1.5 m, the width w is 4.0 m

Answer 1

When we look down into the pool of water from above the pool looks less deep than it really is.
