If green light were scattered more often than any other frequency of light,what color would the sky appear at?

The answer to part one is "green", and the answer to the second part is "green".\n\nThat is why the sky actually appears blue at noon (blue light is more scattered) and red at sunset (red light is less scattered).

There are a couple of theories of why the sky turns green during severe weather; however moreso with hail rather than tornadoes.  Some scientists believe that hail within a thunderstorm cloud bend the light at a degree to create a green tint to the clouds.  Others also believe that the mixture of the water vapor, rain, ice, and hail within the clouds give the cloud itself a bluish tint.  Therefore when you mix the tint with the yellowing and reddening sunset, you get a green tint to the cloud.

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

light green and sky blue...

the atmosphere contains lots of air molecules which scatter the light that passes through them.\naccording to rayleigh, if the size of scattering particle is very very less than the wavelength of light (eg. air molecule), then light of shorter wavelength will be  scattered more than light of longer wavelength.Since in the visible spectrum, blue has shorter wavelength than red....... it gets scattered more than any other color.

I believe that this effect is due more to the amount of atmosphere the light is travelling through, rather than the angle the light is striking the atmophere, or refractive effects. \n\nThe presence of nitrogen and oxygen molecules, which are much smaller than the wavelength of light, in our atmosphere results in Rayleigh-Tyndall scattering, so that the blue light (short wavelengths, closest in size to the scatterers) are scattered out of the mostly whitish sunlight. When the sun is low in the sky, the light from the sun has to travel through more atmosphere to reach us, so more blue and other short wavelengths are scattered out, leaving progressively more yellow, then orange, and finally red sunlight as the sun is lower in the sky. \n\nSo,\n\nwhen the sun is high in the sky:\n(mostly white sunlight)-(scattered blue light)=(yellowish sunlight)\n\nand as the sun drops lower in the sky:\n(mostly white sunlight)-(even more scattered blue light)=(orange or even red sunlight)\n\nThe sky will also appear orange or red when the sun is low in the sky. This is the reflection of the red or orange sunlight from dust, soot and water droplets in the air. \n\nIf the air is full of soot or dust of the right size (about the same size as the wavelength of light), then one does not see Rayleigh scattering, or Mie Scattering (when the particles are much bigger than the light, creating the white of clouds), but selective scattering, when the red is scattered out, creating effects like a blue moon or sun.\n\nWhy the refraction argument will not work:\n- - - - - - - - - - - - - - - - - - - - - - -\n\nThe air layers lowest to the earth are associated with the slowest speed of light, and so as the sun is setting, its light is bent down towards the earth. In fact, the image of the setting sun is actually from the sun after it is below the horizon because of this effect (which is responsible for the green flash, and the strange shape of the setting sun, because of refraction effects). Red light is refracted the least, so in fact if the refraction effect was causing the sun to appear a different color at sunset, it would not make the sun red, but of a shorter wavelength color (like green, hence the green flash).

reflection of light\n\nDuring daylight the sky has the appearance of a deep blue surface, but this is the result of the air scattering sunlight. [1] There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day.

Sky blue\n--------\n\nYou did not check the archive of previously asked questions before you posted your question about the sky's color. This has been asked and answered more than 400 times so far here. \n\nHowever, the reason the sky appears blue (at least most of the daylight hours) is that the atmosphere is mostly oxygen and nitrogen, which are just the right size molecules to scatter the blue light, but let the other colors pass unimpeded. \n\nSo when you take the blue away from the mostly white sunlight, you get sorta yellow sunlight. \n\nAs the sun sets, the sunlight passes through more air, and more blue is scattered away, leaving the sunlight even less blue, that is, more orange. \n\nAs the sun sets even farther, even more blue is scattered away, and the sunlight appears red.\n\nGrass Green\n-------------\n\nFrom the color of chlorophyll, the chemical that plants use to capture energy from sunlight. \n\nEarth Boring\n-------------\n\nIf the earth is boring, then what is not boring to you?

I've heard that the sky turns a type of dirty greenish greyish colour before a severe hailstorm, or a tornado.  But I'd like to think that the sky would do that because of the types of clouds, and the absorption and reflection of light.  I've never seen it myself to say for sure. \n\nI've also been told that there are green flashes that apprear on the sea (but the sea level has to be right) around sunset.  I've never seen one of those either. Apparently, it's one of those must-see things.\n\nAnd then again, another place where greens exist is in the northern lights (Aurora Borealis)...  There are greens and they're gorgeous.  Now I've witnessed that, and it's simply GORGEOUS!!\n\nlike you said, there's always the good old rainbow!  I've seen that too :p\n\ncheers!!

using simple physics\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\nthe grass is green because the other colors are absorbed and only green is reflected. Grass and most other plants are green because they contain a pigment known as chlorophyll.\n\nSun isn't really yellow. The color yellow is a purely human interpretation of a collection of radiation that hits the retinae of our eyes and gets processed by our visual cortex.

.Transmitted 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.When 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.\n\nSo there ya go hun.\n\nSo, why IS the sky blue?.... It is because blue light from the sun strikes the air molecules and scatters and our eyes perceive it as blue.

it is because of tyndall effect as the blue clour as a longer wave length in the spectrum of colours it gets scaterd more in the sky \n \n     \nmxwltan\n6 minutes ago\n\n\n \n The Earth's sky is blue because the air molecules (largely nitrogen\nand oxygen) are much smaller than the wavelength of light. When light\nencounters particles much smaller than its wavelength, the scattered\nintensity is inversely proportional to the 4'th power of the\nwavelength. This is called "Rayleigh scattering," and it means that\nhalf the wavelength is scattered with 2**4 = 16 times more intensity.\nThat's why the sky appears blue: the blue light is scattered some 16\ntimes more strongly than the red light. Rayleigh scattering is also\nthe reason why the setting Sun appears red: the blue light has been\nscattered away from the direct sunlight.\n\nThus, if the atmosphere of another planet is composed of a transparent\ngas or gases whose molecules are much smaller than the wavelength of\nlight, we would, in general, also expect the sky on that planet to\nhave a blue color.\n\nIf you want another color of the sky, you need bigger particles in the\nair. You need something bigger than molecules in the air---dust.\n\nDust particles can be many times larger than air molecules but still\nsmall enough to not fall out to the ground. If the dust particles are\nmuch larger than the wavelength of light, the scattered light will be\nneutral in color (i.e., white or gray)---this also happens in clouds\nhere on Earth, which consist of water droplets. If the dust particles\nare of approximately the same size as the wavelength of light, the\nsituation gets complex, and all sorts of interesting scattering\nphenomena may happen. This happens here on Earth from time to time,\nparticularly in desert areas, where the sky may appear white, brown,\nor some other color. Dust is also responsible for the pinkish sky on\nMars, as seen in the photographs returned from the Viking landers.\n\nIf the atmosphere contains lots of dust, the direct light from the Sun\nor Moon may occasionally get some quite unusual color. Sometimes,\ngreen and blue moons have been reported. These phenomena are quite\nrare though---they happen only "once in a blue moon...." :) The dust\nresponsible for these unusual color phenomena is most often volcanic\nin origin. When El Chicon erupted in 1982, this caused unusually\nstrongly colored sunsets in equatorial areas for more than one year.\nThe much bigger volcanic explosion at Krakatoa, some 110 years ago,\ncaused green and blue moons worldwide for a few years.\n\nOne possible exception to the above discussion is if the clouds on the\nplanet are composed of a strongly colored chemical. This might occur\non Jupiter, where the clouds are thought to contain sulfur, phosphorus,\nand/or various organic chemicals.\n\nIt's also worth pointing out that the light of the planet's primary is\nquite insignificant. Our eyes are highly adaptable to the dominating\nillumination and perceive it as "white," within a quite wide range of\npossible colors. During daytime, we perceive the light from the Sun\n(6000 K) as white, and at night we perceive the light from our\nincandescent lamps (2800 K, like a late, cool M star) as white. Only\nif we put these two lights side-by-side, at comparable intensities,\nwill we perceive a clear color difference.\n\nIf the Sun was a hot star (say of spectral type B), it's likely we\nstill would perceive its light as "white" and the sky's color as blue

The problem is, the air refracts the light as the sun rises. When you see the sun as it rises, it is still actually below the horizon, and it is just that the layers of air are bending the light down so you can see it. The color that gets bent (refracted) the most is the violet light, then the blue, then the green and so on. That is what is responsible for the green flash (since your eye is not as sensitive to the blue and the violet colors, it sees green first). The red actually arrives last, because of these refraction effects. \n\nThe speed of light difference between red and violet is extremely small in air, so this should not have a large influence in the timing, particularly when the atmosphere is only a few tens of miles thick at most (99% of the atmosphere is in the lowest 30 Km).\n\nAfter thinking about this a minute, I realized that you are asking because the sun looks red when it first comes up. This is NOT because the red gets here first. The blue wavelengths are scattered away from the almost white sunlight by the nitrogen and oxygen in the air, leaving the red color. As the sun rises, it goes through less air, and less blue is scattered away, and the sun becomes orange. As the sun rises even higher in the sky, less blue is removed, so the sun looks yellow.

It is called Rayleigh Scattering, or Molecular scattering.  This is primarily caused by oxygen and nitrogen molecules, whose effective diameters are at least 0.1 times smaller than the effected wavelengths.  Rayleigh scattering is most influential at the alitudes above 4.5 km, occuring in what is called the pure atmosphere.  The amount of Rayleigh scattering is highly selective, being inversely proportional to the fourth power of wavelength.  Consequently, invisible ultraviolet radiation, at a wavelength of 0.3 micrometers, is scattered 16 times as readily as red wavelengths at 0.6 micrometers.  In the visible spectrum, blue wavelengths at 0.4 micrometers are scattered about five times as readily as red wavelengths at 0.6 micrometers.  The preferential scattering of blue wavelengths explains why the clear sky appears blue in daylight.  The blue wavelengths reach our eyes from all parts of the sky.

You guys got a lot of it, but the sun is actually green. The atmosphere absorbs much of the light to make it more of a yellowish white light. Pollution and the ozone layer trap and absorb the green light that the sun produces. Then you see what you see. (were you looking at the sun??? :)

Biology will tell you no, but think about this...\n\nI have always wondered, what if the color you see as yellow is the color I see as green?  See, we are all taught colors, so if I was seeing "green" but my parents had always told me it was "yellow,"  I would learn to call it yellow.  So colors could theoretically be relative.  We are taught that they sky is blue, but if we had always been told that they sky was orange, we would think the color blue was called orange.  See what I mean?\n\nThere is probably some biologist out there who can find some way to argue with me about wavelengths of light and ours eyes and something else to try to prove that we all see the same color, but for arguments sake, I like the theoretical argument better.

The earth's atmosphere scatters light.  That is why the sky is black at night (no light to scatter).  If you notice that toward the end of the day at sunset the sky turns orange and red. \n\nThat is because of your viewing angle relative to the light passing through the earth's atmosphere.  Due to the angle of the light from the sun relative to your eye at sunset, the light has to pass through more of the earth's atmosphere.  Orange and Red light have larger wavelengths and are able to penetrate the atmosphere, while blue light is not.  \n\nThat is why the sky is blue during the day, the higher energy (shorter wavelengths) of the blue light cannot escape into space through the atmosphere, it scatters making the sky appear blue.
