why is the sky blue??

Answer 1

http://www.answers.com/rayleigh%20scattering

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 2

As it happens, an excellent book of science history was published just a few months ago, with its theme being the very question you asked. This book, the first by author Peter Pesic, is titled Sky in a Bottle, and explores the efforts by philosophers and scientists from ancient times to our own era to figure out why the sky is blue, and also how to reproduce the color artificially in pigments and dyes (that's the Sky in a Bottle of the title). The book's ISBN is 0262162342 if you want to search for reviews, etc. on Amazon or elsewhere on the Internet.

Answer 3

The light consists of the colors, red, orange, green, blue, indigo, violet. When the sun light hits our atmosphere the light is scattered and because it is relatively thin we only see the higher frequency colors being absorbed. We see blue light. Towards evening or in the early morning when the sun is low on the horizon more of the higher frequency colors are absorbed because the light has travel through the thicker water vapor, smog etc and the sky is orange.

Answer 4

The sky is blue because the atmospheric molecules scatter the blue light which has a shorter wavelength more effectively than all the other colors of longer wavelengths.

Answer 5

It's the speed that the electron circles the
hydrogen atom that makes the sky blue.

Answer 6

the sky is blue because rays of light reflect off of water droplets in the sky

Answer 7

cause the light reflects the ocean which the ocean is blue making the sky blue

Answer 8

Because of the wavelengths that the light passes thru coming thru our atmosphere, it hits the blue in the proper sequence and this is what "our" eye picks up. You must realize, that light is only 1 of a TREMENDOUS spectrum of rays coming right at us, and our eye is adapted for us. Many other animals see in other spectrums of color, or even sound frequencies. You may have a different quantity of receptors for different colors, so we may not even pick up the same "shades or variations" in color spectrums.

So, beauty truely is in the eye of the beholder.

Answer 9

because air absorbs and deflects most of the other colours of the spectrum more than blue. so we get more blue.

Answer 10

It's blue for no reason, according to Bonnie Rait.
