why is sky not red?

Answer 1

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.

The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.

Answer 2

The atsmospere contains a heavy amount of Nitrogen. when the suns rays come into contact with these molecules it excites the nitrogen electrons into higher energy shells (bohr model) and when the atom returns to its stable form it releases that energy with its characteristic wave, which is blue. when there is other molecules in the air, such as in smoggy cities, you can get a spectrum of colors all to do with which molecules are in the air. so you can see reds, oranges, yellows, etc by the same process.

Answer 3

blue happens to be the shortest colour in the spectrum of light that is reflected by our atmosphere and the gasses in the atmosphere. red skies are present only during sunrises and sunsets due to flexability of the spectrum.

Answer 4

The colour blue in the visible spectrum ( white light) is the shortest and is easily refracted by gasses and othe particles.
Therefore you see the blue "light".
Similarly - the mass of water in oceans and lakes refract the blue

Answer 5

because the atmosphere has stuf that makes the sky seem blue. And thats how it should be.

Answer 6

For the same reason grass is not red.

Answer 7

my sister explain this to me once but i didnt get it cause it's to scientific. But the only thing i remember is that is has something to do with the the sun and our eyes. also blue is very pleasant to the eyes.

Answer 8

It's often red.

Answer 9

it has something to do with reflecting light off of clouds and element in the air

Answer 10

yesterday night it is red here
