Upward rays of light in water toward the water–air boundary at angles greater than 48° to the normal are totally reflected. No rays beyond 48° 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?
