Please help!! Look at this diagram of light traveling from a pair of
keys underwater to a boy's eyes. Notice how the light
refracts as it is transmitted from the water into the air.
How does the actual position of the keys compare to the
position that they boy perceives the keys to be in? Do the
keys seem to be shallower, at the same depth, or deeper in
the water than they actually are? Explain your reasoning.
