WHY THE SKY BLUE ?

Answers:

Oxygen and Nitrogen molecules in the Earth's atmosphere scatter blue light much more than red light, so the red light from the Sun goes straight through, but the blue light is scattered in all directions.

We see a blue sky, because of the way the atmosphere interacts with sunlight.

Rayleigh scattering!

The molecules of gases in our atmosphere scatter sunlight; the color scattered the most without being absorbed is blue - that's what we see. When the sun is down, there's no light to scatter - and we see the atmosphere as it truly is - clear.
The effect is called "Rayleigh scattering."

Well, ..., the actual color of the sky is clear ... it has no color and is transparent.

The phenomenon known as Rayleigh Scattering (See: http://en.wikipedia.org/wiki/Rayleigh_sc... explains why the sky is clear and still perceive a clear sky as blue and a night sky as black.

Basically our atmosphere acts as a huge refractive lens. When the Sun is at either horizon light is scattered to towards the red end of the spectrum (longer wave length). This is why we see really rich reds and oranges during the sunrise and sunset. As the Sun rises in the sky light is scattered towards the Blue end ofthe spectrum (Shorter wavelengths). However. if you look a light reflected off of clouds it is white. Additionally, grey clouds appear grey and so forth. At night because there is little light we see the night sky as black. If the sky were truly some other color then everything would appear tinted with that other color. For example, the Martian sky is redder in appearance because of the amount of hematite dust floating around in the atmosphere this causes light scattering to consistently occur in the red end of the spectrum thus it's atmosphere is tinted red.

Simple. Sunlight contains all colors of light. Blue light is scattered by our atmosphere most easily. This is why it looks like there's blue light coming from everywhere in the sky.

OK
.. let's start with the idea of ''refraction of light''.
You know how a rainbow is made up of Red Orange Yellow Green Blue Indigo and Violet.

Well
.. that is refracted light.

''White light'' splits up into the colours that make it
.. and you know that you can ''make a rainbow'' using a prism.

Well
.. the light from the Sun travels through space and hits the Earths atmosphere ..
.. this causes some refraction
.. and the light that comes directly down is the ''blue light''
.. because it has the shortest wavelength
.. so when we look up we see BLUE
.. even though the sky is still actually black and full of stars like it is at night.

In certain atmospheric conditions (dusk and dawn normally) we can see the Orange and Red !

Light from the Sun Contains all the Colors. Blue light has the Shortest Wavelength and is Scattered more in the Earth's Air. It is called Rayleigh Scattering.

Because there is something wrong with you.

Because Allah dangles his balls into the atmosphere.
