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.

k p d has the correct answer - do a search for 'Rayleigh Scattering' and it will explain in detail.

It's nothing to do with a reflection of the seas and oceans, if that were the case the sky above the jungles would be green, white above snow capped mountain ranges, brown above deserts etc.

The sky itself is colorless. After all, the sky doesn't exist as a physical thing. It appears different colors due to the absorbtion and scattering of light. Most of the time it appears blue but in the evenings as the sun is setting and more light is scattered it displays a range of yellows, oranges and reds. If it were possible to see beyond the horizon the sky would be green and very occasionally it's possible to see a green sunset but the atmospheric conditions have to be right. This page has some excellent sky photos including green sunsets... http://mercedes.smugmug.com/gallery/1801150/1/97096645

It was explained to me that the light from the Sun contains all of the colors (think of the light from a prism), the atmosphere absorbs all of the colors EXCEPT for blue. Depending on the angle of the Sun, the moisture in the air, you'll see different shades.

because sun consists of all the colours and the sun reflects and the sky appears blue in colour

because of the fact the sunlight's gentle peaks at yellow. there is extra blue than violet in photograph voltaic to commence with. And our imaginative and prescient (having developed in photograph voltaic) is maximum comfortable to yellow gentle, so we see the sky as blue. That suggested, in case you seem at a sparkling sky in a course precisely perpendicular to the sunlight, it does seem slightly indigo.

There are 3 basic ranges of light. sunlight is blue, incandescent light (regular bulbs) is orange, and fluorescent light is green. The sky appears blue because, quite simply, the light that you are seeing is blue.

actually, the sky is not blue but it's white. Some sky is blue because it reflects from the sea or ocean which is blue..


i hope this helps you....

It is because of the scattering of light According to Sir C.V.Raman It is almost a spectrum

it appears blue in color b'coz of the various gases in the air.
