Question: A bear standing on the side of a very still and clear pond is about to take a swipe at a bass just off the bank. The bear is standing on all four feet and is 50 cm tall. The fish is 30 cm away from the side of the pond and 20 cm beneath its surface.
Part A: Assuming the bear doesn't know Snell's law, how far beneath the water does he believe the fish to be?
