I went diving with a friend recently who was a little disappointed that the underwater world didn’t look as bright and colorful as finding Nemo.

aaah yes, neuroballroomninja, I understand now (again), I heard this before, in a far distant memory of highschool physics, so I kind of forgot... (I hate physics, bluueeh), thank you for explaining ;)NeuroBallroomNinja
Just so you all know this actually is a true story. I was with them on the "everything here is blue" dive. Good times. Oh and by the way Ingrid, rainbows occur because different spectrums of light have a different index of refraction when traveling through certain mediums (like water saturated air). In other words, light has a tendency to bend and change directions when it moves from one medium to another. The amount by which the angle changes depends on a lot of factors. The medium the light is coming from, the medium ... lots moreIngrid
wow, you guys totally got me start thinking about the colours of nature, Does anybody know how rainbow's occure? I know it has something to do with the sun's light on the humid air (so mostly after rain) and the water drops somehow spread the spectrum of light or something. ... moreIngrid
that makes total sence Ryan, and again nice show ;) Does that also mean ozon also absorbes the shortest wavelength best and the wavalenght of blue the least (or maybe even reflects? I always learned an object had to reflect light for it to be seen?) and that is why the ... moreSoul Sister
Very cool. I had always wondered why that was!Ryan
Very slight (translation: totally unnecessary) correction - blue has the shortest wavelength on the visible light spectrum, not the longest - red has the longest. Water absorbs red light to the greatest degree, then orange, yellow, green, and blue to lesser degrees, respectively. Blue light is the least absorbed of all wavelengths of light (visible and invisible) by water, hence the blue appearance. Great idea to bring the light down with you to once again infiltrate the water with the full spectrum of visible light!
