Rays of light moving upward through water toward the water–air boundary at angles larger than 488 to the nor- mal are totally reflected. No rays larger than 488 refract outside. How about the reverse? Is there an angle at which light rays in air meeting the air–water boundary will totally reflect? Or will some light be refracted at all angles?
