5. Bill is swimming and drops his swim goggles in the pool. He looks from above the top of the water to see where they fell and positions himself directly above the goggles. He dives down to the bottom of the pool with his eyes closed so that the chlorine doesn't burn his eyes. He tries several times to retrieve his goggles but comes up empty handed each time. Which interaction of light is distorting the image of where his goggles appear to be?
