why is the sky blue?

Question

I know it has something to do with the water on earth, but I still don't understand it.....

Answer 1

Because I said so.

Answer 2

In the earth's atmosphere there are a lot of dust and other particles floating around. They act like prizms and scatter the the regular sun light into blue, red, orange and violet etc. since blue light is the most closer to U. Violet spectrum and is the visible light having shorest wave lengths, so it travels the farthrest. So even if the light is scattered into many colors of visible spctrum, from far away, that's the only light we see.

Answer 3

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.

wat make the sunset red :)
check this web side it will helps you

( The 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.
However, 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. )

Answer 5

We learned this in science last year. Blue rays of light spread more or something like that. It has nothing to do with the water.

Answer 6

Congrats to those who answered that it is the oxygens in the upper atmosphere,oxygen frequency manifests as blue, just as a flame burns blue when oxygen is added to a fuel.The science kind of guys who have promoted the light reflection theory and passed it down to science teachers as gospel need to wake up and take responsibility for their dis-information. But I have found that most of them will take their lack of knowledge to their grave.

Answer 7

The sky is blue due to the refraction of light on the different layers of our atmosphere. As light from the sun hit's the atmosphere's different layers it bends, or refracts into different colors due to the sudden change of speed.

Answer 8

its one light. pure ligth more like white light which subconciously changes it's color independently only if the color which is in the light combine or show in a right amount for blue sky u need more yellow then red resulting in color of blue are suconsuiously depended on it for its' reson on which light is coming on the right mixture of clors whic only include red yellow and blue which later on u get other colors from diffrent shades of red green and blue and u get the color form light so as long we have light we have color

Answer 9

The blue color is owing to ozone gas in the upper atmosphere, which has the formula O3. Ordinary oxygen, which we breathe farther down below, is O2. This upper-level ozone protects us from harmful ultravioet rays from the sun. Ironically, there are electrical discharges and pollution "down below," which also produce ozone. Ozone at this level is harmful, because it can degrade our goods and ourselves (LOL).

Answer 10

my sky is not blue, I live far far away from the ocean. is that why my sky is brown. Up's I may get busted because I asked a queistion

Answer 11

i think it because it is the reflection of the color of the seas and the oceans on the sky
