Why is the sky blue?

Question

Why is the sky blue?

Answer 1

During the day, the atmosphere scatters the lower frequency lightwaves from the red end of the spectrum away from your eyes while the higher frequency lightwaves toward the blue end of the spectrum can more easily pass through and make it directly to your eyes.

This is why the sky looks red just before sunset. The blue lightwaves from the sun pass straight through the atmosphere over your head, while the red lightwaves get scattered by the atmosphere and deflect down into your eyes.

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.

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 3

The sky is actually not blue, the reason why is it blue is because of the reflection of the ocean and sea.

Answer 4

suzu think of a prism or like the pink floyd alum with the prism on it or a rainbow the colder it gets the color changes now think of our clear ocean as a mirror the suns rays reflects off theocean giving it a blue color because its that far down on the prismatic scale if it was ane dark or any farther itd prolly look purple or even black ^_^

Answer 5

the sky is blue because it reflects oxygen.

Answer 6

Mmmm

Answer 7

Our atmosphere scatters & absorbs the sun's light, and the wavelength it absorbs *least* is the color we see - blue.

Answer 8

You will find it there!
