Why is the sky blue??

Answer 1

Sunlight passing through the atmosphere is refracted; that is to say, it's broken into its primary colors.

"Color" is how our mind interprets different wavelengths of light that strike our retinas (a retina is a part of the eye that contains cells that, upon contact with light, sends an electrical signal to your brain).

On noncloudy days, the wavelength of light that usually passes through the atmosphere with the least reflection and absorption by various chemicals in the atmosphere corresponds to our experience of "blue."

For another tidbit related to this phenomenon, at dawn and dusk, when the sunlight passes through a longer part of the atmosphere (think about a light shining on a ball, and think about the increased horizontal distance to the sides), longer wavelengths tend to predominate in the sky...mostly reds and oranges.

Answer 2

thankyou for asking this Question in actual fact the Sky is all the other colours except Blue which it is reflecting it is merely reflecting the suns electromagnetic spectrum and filtering with our eyes shows Blue like Green Leaves on Plants are absorbing all the other spectrum's etc Green so it is the same with Atmosphere and the ionization layers reflecting Blue which you call the sky cheers Peter

Answer 3

Freddy, this is a good question and here is a short but concise scientific answer for you. First of all visible radiation arriving from the sun is scattered by air molecules, blue through red. Here is the difference. Rayleigh scattering says that scattering is inversely proportion to the fourth power of the wavelength. This means of course that the shorter the wavelength (blue in the case of visible radiation), the greater will be the scattering, if and only if there is no scattering from suspended dust in the atmosphere. This latter type of scattering is referred to as Mie (pronounced me) scattering. I hope this helps you.

Answer 4

Oxygen scatters blue light and absorbs the other colors, so what we see is blue. When the sun is setting, the light comes through the atmosphere at a weird angle, bending the light differently, and that's why we have such beautiful sunsets.

Answer 5

the sky is blue because there are particles in the sky and they make a chemical reaction with the oxygen in the sky.

Answer 6

i am just quessing,maybe its because space is blackish blueish and all that light in space makes it a really sky blue color.
