is the sky purple or blue?

Answer 1

Last I checked it was blue. But it is kinda purple-ish at night.

Answer 2

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Where the sunlight is nearly tangent to the Earth's surface, the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red, at sunrise and sunset.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Individual gas molecules are too small to scatter light effectively. However, in a gas, the molecules move more or less independently of each-other, unlike in liquids and solids where the density is determined the molecule's sizes. So the densities of gases, such as pure air, are subject to statistical fluctuations. Significant fluctuations are much more common on a small scale. It is mainly these density fluctuations on a small (tens of nanometers) scale that cause the sky to be blue.

Answer 3

i don know man..is there a sky at all? i see clouds, some of them white, others grey..
but is there a sky? wht do we refer to as the sky? the emptiness which no end has been yet found? the space? we see a blue color because of the gases n stuff in the atmosphere..the sky is something imaginery.. so far, there is no end to wht see when we look into the space! the furthest point that the strongest telescopes see is, yet, emptiness and stars

Answer 4

The sky is just a colourless layer of air. The light from the sun scatters away in this layer and we see it as blue. actually it is the ultraviolet rays and so we can say it that the sky is violet in colour.

Answer 5

Blue because whenthe sun reflects the ocean the sky becomes blue.

Answer 6

i think the sky, for some reasons, has many differnt colors. when it's a beautiful day outside, the sky is blue, when the sun is setting
, i see pink and when it's going to rain, it's gray.

Answer 7

Sky is any color you want it to be. I know for some people it is always gray! :))

Answer 8

Neither

Answer 9

blue... reflecting from the ocean

Answer 10

When it sunny its blue.When its raining its gray.
