why does the sky appears to be bleu during day time when rest of the space is covered with darkness?

Question

why is the colour of the sky blue?

Answer 1

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. In space, there is no atmosphere to separate colors from the white light and space looks black.

Answer 2

The sky only appears to be blue because of the way that the light from the sun is filtered though the various gases in the atmosphere.Basically each gas in the atmosphere reacts differently to being bombarded by sunlight.The main hue coming through the spectrum is blue,this is why the sky appears to be blue.

Answer 3

As discussed previously white light enters the atmosphere. Gases in the atmosphere (N2) disperse blue light more than red. The dispersed blue light is then absorbed and re-emitted from similar gases in other paarts of the atmosphere, thus appearing to emit from all over the sky. At sun set and sun rise the light from teh sun passes through teh most atmosphere to reach our eyes and thus a large portion of the blue light has been dispersed, hence the sun during sunset and sunrise appears redish.
Hope this helps.

Answer 4

When light travels in transparent solids and liquids it gets scattered by interactions with the air molecules in a process called Rayleigh scattering. Since blue light is scattered more than red light, most of the light you see in the sky when you are not looking directly at the sun is blue. In space where there is no air, you see no light at all unless you are looking directly at the sun.
