Y is the sky blue?

Answer 1

from the light reflecting off the water molecules in the atmosphere..

Answer 2

The sky appears blue because of the light from the sun is scattered by small particles in the atmosphere.The amount of scattering depends upon the wavelength .Accordingly the blue light which has the lowest wavelength in the solar light spectrum is scattered the most.So the sky looks blue.This also explains why the sky is red at sunset.The light has to travel through more atmosphere before it reaches us, at the time of sunset.So the blue light is completely scattered away by that time and only the red light remains.

Answer 3

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.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Answer 4

Why is the sky blue: Summary
So, why is the sky blue? It is because blue light from the sun strikes the air molecules and scatters and our eyes perceive it as blue.


Why is the sky blue: Short Summary
Why is the sky blue, you ask? Blue in sunlight collides with air molecules and our eyes see it as blue.

Answer 5

It is according to Raleigh scattering law. It states "that the Amount of scattering is inversely proportional to the fourth power of its wavelength." As the blue light is scattered more in the atmosphere (due to shorter wavelength) , the sky appears blue. If someother colour is scattered more it will be in someother colour.

Answer 6

dont you watch the commercial where the little girl explains why the sky is blue ?

Answer 7

it's simply because blue sky is the reflection of the ocean deep...the deep see...so that's it....a reflection......

Answer 8

it is simply because,it's not green or red =)
