Can the sky be white

Answer 1

The first steps towards correctly explaining the colour of the sky were taken by John Tyndall in 1859. He discovered that when light passes through a clear fluid holding small particles in suspension, the shorter blue wavelengths are scattered more strongly than the red. This can be demonstrated by shining a beam of white light through a tank of water with a little milk or soap mixed in. From the side, the beam can be seen by the blue light it scatters; but the light seen directly from the end is reddened after it has passed through the tank. The scattered light can also be shown to be polarised using a filter of polarised light, just as the sky appears a deeper blue through polaroid sun glasses. This is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering--after Lord Rayleigh, who studied it in more detail a few years later. He showed that the amount of light scattered is inversely proportional to the fourth power of wavelength for sufficiently small particles. It follows that blue light is scattered more than red light by a factor of (700/400)4 ~= 10.

Answer 2

It is clear but it look blue because it is far away.....actuley, everything around us is clear/white.....even humans and animal's........it is just light that gives everything color.... Hope this answer helps
this information I didn't believe at first but it is truthful. the sky's colour is actually red. the only reason why it isn't is because the water reflects with the sun creating the colour blue in the sky. but the only time you see the red is when the sun is going down.

Answer 3

Black, if looking away from planet earth.... but then that is not the sky, that is looking at "space" itself. Whe looking at the earth, the "sky" (as ground-walkers see it) is not visible to folks up there in space... what they see is the oceans, the land and mountains, and clouds. So what colour? Clear, I would have to say.

Answer 4

No, it is actually clear. It only appears to be blue due to refraction.

1. Outer space contains virtually no gas/dust to scatter light.

Outer space is black.

2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective.

If it looks blue, then it is not clear (!)

The colour is due to scattering, not to refraction.

3. If the sky's colour was due reflection from the oceans, then it would be white above Antarctica, which is snowy white.

Answer 5

The sky changes color because, when the sun is shinning light, the colors that it uses have certain energy. when the sun is just rising, the sky is a orangery color, when the sun is above our heads, the shy is blue, when the sun is setting, then it turns red again. red is the color with the most energy so it can go through the junk in our atmosphere. when the sun is above us, the sun doesn't have to give much energy.

Answer 6

The color of the night sky is Navy Blue (dark Blue) Because the day sky is Light Blue it only gets darker if the sky was black at night we'd have a gray sky during the day

Answer 7

The sky is blue.

Clouds, however, can be green.

(see the related link)

Answer 8

Yes, because of the storm and of the clouds in the sky.

Answer 9

no lol
