It's because blue in this set of visible light reflects the sun's light, and that is what we see. Technically, every color in the rainbow is the sky. That's why we see a rainbow when it rains, or there is water, because then all the colors reflect.
Correct.
. and for you who say it reflects the ocean... i believe that it is the other way around
I agree. The sky does not reflect the ocean, the ocean reflects the sky.
Now, there have been people commingting the same reason in different lengths and qualities, there have been people who have not listened in physics. There have been people who have plainly gone around everything and made up something for the lulz, and there have been people commenting on the colour.
The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
Actually, the sky is just plain scattered light from the sun. The light is reflected off from clouds, the ground,etc. So the sky is just plain (for some reason blue) scattered light!
Well Billy, the sky is blue because God cried too much when Eve ate some bad fruit, and there was something about a snake...the end.
Now onto the thread, the sky is blue because light scatters, and while most colors make it through the atmosphere, blue visible light rays are shorter than others so it can stay in the sky when light scatters.
well, there are many different layers... this is just because of the sun and the type of atmosphere were in... if you go higher, the color of the sky changes O_O
