Question

Why is The Sky Blue

*Close* spelling error

Answer 1

The sun's rays hit the Earth's atmosphere, where the light is scattered by nitrogen and oxygen molecules in the air. The blue wavelength of this light is affected more than the red and green wavelengths, causing the surrounding air to appear blue. At sunset, the sun's light passes farther through the atmosphere, deflecting and decreasing the blue in the air. Scattering by dust particles and pollution in the air causes the sunset to appear red.

Answer 2

Why is the sky blue?
(Lansing State Journal, March 20, 1996)



--------------------------------------------------------------------------------

The earth has a protective blanket of gases, water and dust called an atmosphere. The blue color of the sky is a result of sunlight passing through and interacting with the atmosphere.
If you look at sunlight through a prism, you will find that "white" sunlight is actually composed of a rainbow of colors.

Light can be described as a wave, and different colors of light correspond to different wavelengths. For example, red light has a long wavelength compared to blue light. As sunlight passes through the atmosphere, the atmosphere selectively filters blue light using a process called scattering. An example of scattering can be seen in a smoke-filled room. When light enters the room, the smoke particles scatter the light, resulting in shafts of visible light. The smoke particles, however, have little effect on the color of the scattered light.

Selective scattering (preferential scattering of one color of light over other colors) occurs when light scatters off particles that are much smaller than the wavelengths of the colors. In the case of our primarily nitrogen filled atmosphere, the shorter wavelengths (blue) are scattered much more strongly than the longer wavelengths (red). Thus, as sunlight passes through our atmosphere, blue light is preferentially scattered, and becomes visible to the eye.

Answer 3

The way light is dispersed through the atmosphere causes the sky to appear blue to the human eye, or so learned ones say.
I think it's because God liked blue, and wanted it that way.
LOL.
Have a great day!

Answer 4

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light.

Answer 5

Sky Blue, the pornstar?

Answer 6

Air molecules reflect blue light

Answer 7

Exactly the reason why oceans are blue. There is somethin common in both.

Answer 8

sky blews us so it's blue in colour

Answer 9

Because it matches your pretty blue eyes!

Answer 10

because it has the weight of the world on its shoulders (blue as in sad)
