AHHHH !!!!A question other than why is the sky blue.  The color of the sky is colorless, clear.  Look at the shots of earth from space (on the night side) you can see earth perfectly, no color enhancement.  Look up at the stars on a clear night, you can see them without any bluish color.\n\nThe sky is only various colors when the sun is shining thru it.

The sky is blue to us beause of Rayleigh scattering.  From outer space, you don't have that atmosphere effect, so it's black.

The sky is blue because of scattering of the sunlight by the atmosphere. According to Raleigh's law," The amt of scattering is inversely proportional to the 4th power of wavelength".Hence the shorter wavelengths r scattered much more than the longer ones. According to Raleigh's Scattering Law,blue light is scattered to a greater extent than red light. This scattered radiations causes the sky to appear BLUE.

I answer this question nearly every day.  *sigh*  :) :)\n\nThe 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. \n\nHowever, 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. \n\nAs 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.

Is water wet? Is the sky blue?\n\nYEP!

Why is the sky blue: Discussion \nTransmitted light (from the sun, light bulbs, fire, etc) is made up of a spectrum of colors. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum.\nWhen transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.\nOur eyes contain thousand of rods and cones, which are the receptors for light. Whenever one of the 3 Stooges pokes you in the eye you see a giant blue spot. This is because the blue receptors have been activated. Blue is one of the primary colors and thus more easily activated and seen by our eyes.

Particles in the air refract the white light of the sun into the spectrum.  The sky is blue because blue gets through the easiest.

There is no such as the "real" color of the sky. The reason the sky is blue during the day is because the color of the light that the sun shines is white. And as you may know, white is the presence of all color and black is the absence of color.\n\nSo, the white light that the sun emits contains every possible color of light.  Now, each color of light has a different wave length depending on where it is on the color spectrum.  Red light has the longest wave length and blue/violet light have the shortest.  And since blue light has the shortest wave length, you see more of it's waves.\n\n\nsorry... that's the best i can explain it

The sky is blue because of the ozone layer, which is blue. The ozone layer is blue because (have you ever tried to shine light through a triangular pyramind (glass)?) It filters everything but blue color...why? I don't know. Uh...I'm not sure, probably because they want to know more about female sex organs because girls have 2 and we have 1 ugly sex organ that's not exactly as attractive as girls. Not that I'm a pervert...only nerds are.

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. \nWhere the sunlight is nearly tangent to the Earth's surface, the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red, at sunrise and sunset.\n\nso\n\nAn old weather predicting adage rhythmically states: \n\nRed sky at night, Sailors' delight.\nRed sky in morning, Sailors take warning. \n\nHumidity in the air is indicated by red skies at sunset-- red sky at night-- or, at sunrise-- red sky in morning. The forming raindrops scatter the short-wavelength blue light so that only the long-wavelength red light reaches the observer.

1. Why the sky is blue.\nWhen light passes through a medium with molecules much smaller than the wavelength, it is scattered. You can understand it so: the light begins by going as a beam "forward". It gets absorbed for a moment by a molecule and then emitted again in whatever direction. This effect is more effective when the wavelength is shorter. Blue light has a wavelength ~2 times shorter than red light and gets scattered 16 times as effectively. So the beam coming directly from the sun is deprived of blue =>thus it is yellow (or red if it is sunset and it has passed a thick layer of atmosphere (geometry)). From all other directions we see the light that was going towards other points on the Earth. The yellows and reds went on and the blue was sent in other directions, including towards us.\n\n2. Why the grass is green.\nGreen plants use light to make food. The light is absorbed by chlorophyll (two types of it, too and a bit different, but no matter). Chlorophyll absorbs violet, blue, orange and red light. What we see is what was not absorbed, but reflected. If you take the aforementioned colours out of the white light spectrum, you get a mixtureof green and yellow. And green is the colour our eyes see best. Thus - green grass.\n\nI hope I've been clear

The nitrogen and the oxygen molecules in the air have the right dimensions to scatter blue light, but other colors pass through with little problem. So this causes the sky to look blue. \n\n(whitish sunlight)-(blue light scattered)= (yellowish sunlight)\n\nAs the sun sets (or rises), the sunlight passes through more air, and more blue light gets scatted, so the sunlight looks closer to orange or red\n\n(whitish sunlight)-(even more blue light scattered)=(red or orange sunlight)

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.\n\n\nBecause the universe is not infinitely old, that puts a limit to how long the\nlight from all those stars can have travelled. So some of the light has not\ngotten here yet. Because stars do die out, that means that their light dies\nout too - which means that we may get the light from some stars at one time,\nand the light from some other stars at a different time, but not all the \nlight\nof all the stars that everywhere put together. Finally, because the \nuniverse is\nexpanding, the light gets weaker before it gets to us. All in all, this means\nthat there is not enough light from all those stars to make any point in \nspace\nbright.

The sky is blue because the nitrogen in the air scatters the blue light out of sunlight. \n\nOur sun is a yellow star, so it has slightly yellow light, but it is still pretty close to white light.\n\nSunlight on earth is slightly yellower than it is in space because some of the blue light in sunlight gets scattered out by the presence of nitrogen in the air, making the sky appear blue. So \n\n(White light) - (Some Blue light) = (Yellow light)\n\nAs the sun sets, the sunlight travels through more air, and the nitrogen scatters out more blue light and the sun appears first orange, and then finally red.\n\nAs the sun starts to set:\n\n(White light) - (More Blue light) = (Orange light)\n\nand finally as the sun has almost set:\n\n(White light) - (Lots of Blue light) = (Red light)

Yes! Of course here in the UK it is not always 'blue' below the clouds! \n\nThe reason for the sky being blue is that 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. \n\nHowever, 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. \n\nTo get a fuller explanation (if you can bear it!) see the link below.\n\nGood question!\n\nx

Neither is blue. \n\nThe SKY\nThe blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through.

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. \n\nThe Sea.\nParticles and solutes can absorb light, as in tea or coffee. Green algae in rivers and streams often lend a blue-green color. The red sea has occasional blooms of red Trichodesmium erythraeum algae. \nParticles in water can scatter light. The Colorado river is often muddy red because of suspended reddish silt in the water. Some mountain lakes and streams with finely gound rock, such as glacial flour, are tourquise. Light scattering by suspended matter is required in order that the blue light produced by water's absorption can return to the surface and be observed. Such scattering can also shift the spectrum of the emerging photons toward the green, a color often seen when water laden with suspended particles is observed. \nThe surface of seas and lakes often reflect blue skylight, making them appear bluer. [[[ Montana reflection.]]] The relative contribution of reflected skylight and the light scattered back from the depths is strongly dependent on observation angle.
