Answer 2

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.
Our eyes contain thousand of rods and cones, which are the receptors for light. Whenever one of the 3 Stooges pokes you in the eye you see a giant blue spot. This is because the blue receptors have been activated. Blue is one of the primary colors and thus more easily activated and seen by our eyes.

Answer 3

The molecules that make up our atmosphere are the right size to scatter that blue wavelength of light, which is why we see it from all directions in the sky. the same reason why the sun appears yellow from earths surface but white from space. Remove that sky blue from white light and you are left with yellow.

Blue is also how I feel when my baby leaves and my hound dog dies. Also, how I feel when the cops pull me over and I see their blue lights flashing in my rear view mirror. Then, again, blue is the color of the K-mart special, so this color isn't all bad.

Answer 5

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 6

The nitrogen in the atmosphere scatters the higher frequency light (blue) more than the lower ones. So when you look at different parts of the sky, you're seeing blue light from the sun that has been scattered randomly.

Answer 7

Light coming from the sun is what's called "white light" White light contains all the colors of the rainbow. When it enters Earth's atmosphere this light is separated into its individual colors by chemical elements in the atmosphere and scattered across the sky. Nitrogen is the most abundant element in our atmosphere, and that element scatters the color blue across our sky more than the other colors. In space, there is no atmosphere to separate colors from the white light and space looks black.

Answer 8

Refraction of sunlight. At sunrise or sunset, the sky is all colors. But when you see the sun outside of those hours, all you see is blue sky because the color you see is scattered by air. On Mars, with its thinner air, the Mars rovers have shown us color-corrected pictures of a pink-violet sky.

Answer 9

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 10

the sun reflects the ocean. the ocean is blue
