Why is the sky blue?

Answer 1

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

The wavelengths of sunlight. As they move through the atmosphere, the waves hit dust particles in the air and the waves Stop, because they hit something. Because Blue is a longer, more gradual sine wave, the blue waves hit fewer dust particles, so the blue wave gets through our atmosphere. Therefore, the sky looks Blue. The sun looks yellow because the waves are coming straight at you, therefore more waves get through. Other places in the sky, the waves are moving ACROSS the sky, so the other waves hit the dust motes.

Answer 3

A clear, cloudless daytime sky's blue because molecules of oxygen and nitrogen in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colors because the blue light has been scattered out and away from the line of sight. The molecules are able to scatter because the electromagnetic field of the light waves induces electric dipole movements in the molecules. To further explain this, the cones in our retina the color receptors are more strongly stimulated by the blue wavelengths.

Answer 4

Sunlight entering the atmosphere on an angle is scattered by molecules in the atmosphere; blue light is most easily scattered in these circumstances, and so the sky appears blue.

Answer 5

It not Blue. It is actually iridescent. It only look Blue because of the angle we see it from. Well, then again, it could be how the atmosphere diffuse the light spectrum similar to a Prism on Pink Floyd's album "Dark Side of the Moon".

Answer 6

The sky was "blue" because no one would play with it

Answer 7

Mother Nature's choice

Answer 8

reflection of the water from the sun onto the sky. thats why its dark at night when there is no sun up.

Answer 9

Gasses

Answer 10

It's to do with short and long light waves reflecting in the atmosphere.
