why is the sky blue?

Answer 1

The color of the sky is a result of diffuse sky radiation which turns it a light violet color. It appears blue because human eyes cannot see deeply into the Violet range and sees colors closer to green the best. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering).

Because of the strong wavelength dependence (inverse fourth power) in Rayleigh regime light scattering according, one would expect that the sky would appear more violet than blue, the former having a shorter wavelength than the latter. There is a simple physiological explanation for this apparent conundrum. It turns out that the human eye's high resolution color-detection system is made of proteins and chromophores (which together make up photoreceptor cells or "Cone" structures in the eye's fovea) that are sensitive to different wavelengths in the visible spectrum (400 nm–700 nm).

Answer 2

Excellent question. First of all visible radiation arriving from the sun is scattered by air molecules, blue through red. Here is the difference. Rayleigh scattering says that scattering is inversely proportional to the fourth power of the wavelength. This means of course that the shorter the wavelength (blue in the case of visible radiation), the greater will be the scattering, if and only if there is no scattering from suspended dust in the atmosphere. This latter type of scattering is referred to as Mie (pronounced me) scattering. I hope this helps you

Answer 3

because the sky wants to be blue it is its favorite color

Answer 4

bc it reflects blue light particles.

Answer 5

water in the air

Answer 6

The same reason why the grass is green. xoxoxo
