Wave Refraction: Air to Water
A wave changes direction (closer to the normal) as it passes to an optically denser medium, in this case from air to water. This is because light travels more slowly in the denser medium. The refractive index is the speed of light in a vacuum divided by the speed in the medium. The refractive index of water is about 1.33.
