That's an interesting question you posed on the refraction of light in water, Whidden. I wonder that myself... It might be the change in pressure in the water the deeper you go, which might cause further refractions, to the point where the light gets basically reflected back upwards after a certain depth? Or just all the matter that the light has to filter through, even though the water is so transparent?
I'm guessing that the clearer water is, the easier light passes through it. Perhaps that's why Loch Ness is so dark (its murkiness blocks the light quickly), while the shallows of the caribbean are so clear that you can see right to the bottom?
there you go ... bingo ... the planton and all the very small creatures cast shadows ... and the deeper you do the more planton gets in the way and the darker it gets ... thats just an idea
I dunno, I guess it becomes radiation, or heat, turns into energy when it slows down in the water, or in the back of your eyeball, or when it hits a rock.
It's just crazy stuff, it can travel 13 billion years with little or no loss of stability, (which seems powerful), then as soon as it hits some water, or your eyeball, it turns into....Heat?
I should have listened in High School, they taught us all this stuff, I could have cared less back then.
