![]() Now the situation isn't quite so simple as a bunch of parallel rays reflecting off of a mirror. I can think of another possible effect that could contribute, even if the water were perfectly calm: on its way in from the Sun, light goes through the atmosphere, which has varying density/temperature, and so also varying refractive index. In practice, the surface is never perfectly calm, so the effect from ripples always comes into play at least a bit. ![]() ![]() ![]() You'll see an image (or piece of an image) of the Sun anywhere the surface of the water is oriented such that the angle between the Sun and the water and the angle between the water and your eye are equal:įor water with many ripples, there will be many such locations, but most will be along the line between you and the Sun, or close to it. ![]()
