Why is the sky blue?

Question

Thanks everyone!

Answer 1

Believe it or not, the sky is actually purple!!! We see it as blue because we cannot see ultra-violet, the next best thing is blue; that is the highest frequency of light that we can see. Its all about the wave length hitting the atmosphere.
Thanks for reading.

Its not water in the sky, I promise.

Answer 2

You would think that after this question had been asked more than 5600 times people would know the answer by now but we still get the "reflection off the oceans" line. The answer is Rayleigh scattering, the various wavelengths of light are scattered by the gas molecules of the atmosphere. Blue is scattered the most so we see the blue colour as dominant. As the sunlight takes a longer path through the atmosphere in the morning and evening, the blue is scattered away leaving the red end of the spectrum which is why the sky goes from blue through green yellow and orange to red at sunset.

Answer 3

The colour of the sky as seen from the earth is due to the scattering of sunlight by the molecules of the gases in the earth's atmosphere.The amount of scattering is inversely proportional to the fourth power of the wavelength.This is known as Rayleigh's scattering law.Hence the shorter wavelengths are scattered much more than the longer wavelengths.The shorter region of the solar spectrum is blue in colour.This scattered radiation causes the sky to appear blue.

Answer 4

The sky is blue because the sun reflect on the ocean right. And the ocean is blue right. Soo the reflection of the ocean makes the sky blue. Simple as that =D

Answer 5

The sky is blue because water particles reflect blue light.

Answer 6

Because the ocean reflects its blue-ness onto the sky. Or something like that.

Answer 7

As light travels through our atmosphere it is refracted (think prism) into different colors. During the early part of the day you can see purple, red, orange, yellow and blue and the reverse in the evening. Whichever light waves are most refracted appear to the human eye. The colors of plants are based on their absorption of these colors as well. The angle of the sun in the fall makes leaves absorb orange and red until they burn brown and fall off of the branches.

Answer 8

DJG is close -- it's blue because there's no red.

the red gets scattered in the atmosphere which is why we have red when the sun or moon is low in the sky.

So the sky really is blue because it's not red! ;)

Answer 9

lol @ ocean reflection answers. Its due to light scattering.

Answer 10

something to do with reflecting from the oceans
