Why the color of sky is blue ?

Answer 1

Always a popular question for the sincerely gentle yet lost soul, jokesters, the lazy or Google-impaired.

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.

Please don't follow up with questions about the speed of light and your car's headlights...

Now be off with you and go with God my kindly but simple child.

Answer 2

Light coming from the sun is "white" light, which means it is all colors. Our atmosphere has the right composition to disperse the incoming blue light waves all over the sky. The remaining light coming from the sun tends to look more yellow than white because the blue light waves are missing by the time it reaches our eyes (if we are foolish enough to look directly at the sun!).

Answer 3

The 'sky' is actually atmosphere. The atmosphere is made up of dust . water vapor and even some little critters.
the color we see is the sunlight and reflected light shining through all of this 'stuff' and the blackness of space behind it .
Any way that is how I explain it to the Grandkids .

Answer 4

this is due to the dispersion of white light by water droplets
