why is the sky colored in blue?

Answer 1

As it reflects blue colour and absorb all the other colours.

Answer 2

In the earth's atmoshpere, virtually trillions upon trillions of particles of dust are suspended. The sun is the earth's primary source of light. The type of light the sun puts out is called white light. It is the result of orange, green, red, violet, indigo, blue, and yellow light combined. Every light has a certain wavelength, that is, the particles of light travel at different frequencies and amplitudes. Blue has the lowest frequency. For this reason, it is the major component of white light that is broken up by these dust particles the easiest. That is why the sky is blue. Throw is factors like clouds and atmospheric moisture combined with the sun and other colors are visible. This is how sunsets and sunrises show off their splendid colors. The reason that only sunsets and sunrises have these colors is this: When the sun shines at its zenith (highest point), it only has about 100 miles of atmosphere to shine through. However, when the sun is low on the horizons, light must travel through a much greater amount of atmosphere, which allows not only blue, but also red, orange, and yellow colors to be displayed. That was officially the longest answer to any question that I've ever made, so I'm gonna stop now.

P.S. Oceans have absolutely nothing to do with it. If it was their reflection, which it isn't, wouldn't people in the middle of Asia see nothing?

Answer 3

This is a very simple question with a complicated answer. Glad you asked. :-)
The sky is blue because of the properties of light. Light travels in wavelengths. Each color of light has a different wavelength. When all of the colors are mixed together the light appears white. Direct sunlight is white. When sunlight (white light) hits the earths atmosphere, it is refracted into different colors. This may be hard to understand so I will put it a different way.
The same white light is redirected through water also. You may know of this process as a rainbow. White light hits the raindrops, and each color is refracted making a wide variety of colors. This same process applies to the color of the sky. That is why at night the color of the sky is black (meaning no light), in the morning and in the evening the color of the sky is red and orange, and at dusk and dawn the color of the sky is dark blue and purple.

Answer 4

(oh goodness!)

The ski looks blue, because molecules in the air scatter blue light from the sun (more than they scatter other color light- mainly red; Longer wavelength)


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

Answer 5

That's the atmosphere working for you, 24x7. As sunlight passes through it, the air molecules scatter the blue light, making they sky look blue. As you go higher and higher in the atmosphere, it gets less blue, more like the black of space.

Answer 6

It doesn't deal with light reflecting from the sea/oceans. It does however involve reflection/absorbtion of light. Light passes through out atmosphere and wavelength for blue is reflected giving us our blue sky.

Answer 7

It has something to do with the spectrum of the sky. The sky is blue due to its position in the spectrum.




Diffuse sky radiation is solar radiation reaching the earth's surface after having been scattered from the direct solar beam by molecules or suspensoids in the atmosphere. Also called skylight, diffuse skylight, or sky radiation. Of the total light removed from the direct solar beam by scattering in the atmosphere (approximately 25 percent of the incident radiation), about two-thirds ultimately reaches the earth as diffuse sky radiation.

Scattering is the process by which small particles suspended in a medium of a different index of refraction diffuse a portion of the incident radiation in all directions. In (elastic) scattering, no energy transformation results, only a change in the spatial distribution of the radiation. The science of optics usually uses the term to refer to the deflection of photons that occurs when they are absorbed and re-emitted by atoms or molecules.

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Where 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.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Individual gas molecules are too small to scatter light effectively. However, in a gas, the molecules move more or less independently of each-other, unlike in liquids and solids where the density is determined the molecule's sizes. So the densities of gases, such as pure air, are subject to statistical fluctuations. Significant fluctuations are much more common on a small scale. It is mainly these density fluctuations on a small (tens of nanometers) scale that cause the sky to be blue.

Neutral points
There are three commonly detectable points of zero polarization of diffuse sky radiation (known as neutral points) lying along the vertical circle through the sun.

The Arago point, named for its discoverer, is customarily located at about 20° above the antisolar point; but it lies at higher altitudes in turbid air. The latter property makes the Arago distance a useful measure of atmospheric turbidity.
The Babinet point, discovered by Babinet in 1840, typically lies only 15° to 20° above the sun, and hence is difficult to observe because of solar glare.
The Brewster point, discovered by Brewster in 1840, is located about 15° to 20° directly below the sun; hence it is difficult to observe because of the glare of the sun.

Under an overcast sky
There is essentially zero direct sunlight, so all light is diffuse sky radiation. The flux of light is not very wavelength dependent because the cloud droplets are larger than the light's wavelength and scatter all colors approximately equally. The light passes through the translucent clouds in a manner similar to frosted glass. The intensity ranges (roughly) from 1/5 of direct sunlight for relatively thin clouds down to 1/1000 of direct sunlight under the extreme of thickest storm clouds.

Answer 8

the water droplets in the atmosphere reflect the blue end of the spectrum

Answer 9

becuse the sun emits red and blue light rays but the blue ones only mke it through

Answer 10

baby thats the way it is.the birds sing the sky is blue and u got to give it all hell
