Why is the sky blue?

Answer 1

due to light waves. the same reason applies at susnet when it becomes orange.

Answer 2

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.

Answer 3

The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust. As sunlight goes through the air, it bumps into the molecules and dust. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. The blue light gets scattered all around the sky. When you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light the sky looks blue.

Answer 4

Our atmosphere tends to scatter short wavelength light and let long wavelength light pass through. The color blue has a short wavelength and so the blue light is scattered in the atmosphere so it is sort of stuck floating around in the sky. That is why we end up seeing a blue sky.

Answer 5

Our atmosphere tends to scatter short wavelength light and let long wavelength light pass through. The color blue has a short wavelength and so the blue light is scattered in the atmosphere so it is sort of stuck floating around in the sky. That is why we end up seeing a blue sky.

Answer 6

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Answer 7

At first it worse to mentioned that sky should be always dark as it is look in night, BUT due to the scattering of light from the sun (reflection by the dust) it has a blue color.

Answer 8

At first we go through the physics,these type of factors deals with scttering of light according to its wavelength.During morning and evening time the amplitude becomes high and wavelength also gets higher s its appear red according to scattering of whtie light in to seven colors. At the same time at noon the earthplace it on centre of light rays from the sun wavelenght is low ao it appear blue

Answer 9

roses are red, violets are blue. Don't ask questions you already know.

Or you don't for serious

Answer 10

You know blue color then is blue.

It was unkown color...but we know that is blue color only.
