Answer 2

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.

Answer 3

It's because the sky absorb every seven colour's in the light except blue so the sky reflect blue colour.

Answer 4

With clear sky and sun overheaded, incoming solar radiation strikes the atmosphere and scattered into atmosphere in their blue range of their electromagnetic wave length. That is why the sky is blue.

Answer 5

When transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.

Answer 6

have you ever seen a sunset its like an explosion of deep red and orange with amazing yellow, it truly breathtaking, so its not really blue all the time, i don't know why things are the way they are but i suppose that proves there is something out there(God)

Answer 7

Because it looks better blue, though it is not really blue, we only imagine it is.

Answer 8

molecules in the air scatter blue light from the sun more than they scatter red light

Answer 9

just search that in the questions tool bar, but not all of the answers are correct.. usually the best answers are correct

Answer 10

It's not, its actually green,

our eyes perceive it to be blue.

Answer 11

Because it is the lowest color point and the shy makes it the highest color piont ( thats what i heard)
