Answer 2

the sky we see is our atmosphere and .The real color of the sky is black (space) that mean we suppose to see space when we look to the sky but we have an atmosphere.

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere most of the longer wavelengths pass straight through. Little of the red orange and yellow light is affected by the air.

However much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead the sky looks blue so this blue sky we see is our atmosphere.

Answer 3

Air molecules scatter sunlight preferentially in the blue.
