Why is the Sky Blue ? .. i don't know really.. lol?

Answer 1

Water vapor in the atmosphere.

Answer 2

Do you really wanna know........
Here it is

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.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Answer 3

You may already know that sunlight is actually made up of all the colors of the rainbow: red, orange, yellow, green, blue, and violet. You probably also know that sunlight has to pass through our atmosphere before it reaches our eyes. The gas molecules in the atmosphere break up, or "scatter" the sunlight into its many parts, and they react differently to different colors. Different colors of light have different energies, or wavelengths. For example, red light has a long wavelength while blue light has a short wavelength. The gas molecules in the atmosphere scatter the blue wavelengths better than the red wavelengths. So the sky looks blue.

Answer 4

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 5

I really don't think that sky is blue. These are the result of sun rays, and other environmental effect mixed to-gather. Like ocean. Water is not blue, but oceans seem to be blue. Just my opinion.

Answer 6

Honestly...

Answer 7

Lights and the steam whcih wrap the earth.
The wrap actually is steam of water which like a filter, and only allow bule

Answer 8

because of the dust in the atmosphere scattered the shortest wavelength, that why the sky is blue.

Answer 9

It's not always blue. Sometimes it's gray, and sometimes it's white (especially here in the SF Bay Area where we get a lot of fog).
