what color is the sky?

Answer 1

It is difficult to define precisely for several reasons. During daylight the sky has the appearance of a deep blue surface, but this is the result of the air scattering sunlight. There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day.

Answer 2

The first question you should ask is "what is sky"? The region of atmosphere we see above us is sky, generally. This appears blue to us. If we go up and try to see up, everything is black/dark. It is the dispersion of sunlight in the atmosphere by different kinds of particles/molecules that makes the 'sky' appear blue.

Answer 3

Violet. The sky appears blue because of the way the atmosphere "scatters" the incoming sunlight, our eyes perceive this as blue because the human eye can not detect these wavelengths in the presence of the blue wavelengths.

Answer 4

The sky is clear but it reflects the water in the atomsphere which makes it appear blue.

Answer 5

Answer 6
