Why is the sky blue?

Question

It is because of some energy thing or what

Answer 1

why oh why is the sky b-l-u-e blue?
I'll t-r-y to supply the scientific point of view
the sun sends out the sunlight
the sunlight looks like one light
but science says that sunlight has all the colors of the rainbow
each color has a wavelength, each one a different wavelength
blue has a different wavelength of all the colors of the rainbow
they leave the sun together as they travel far and near
blue light is reflected when it reaches the atmosphere
the atmosphere around us reflects the blue that found us
that's why the sky is blue
and not the colors of the rainbow.

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

Because the water in the atmosphere absorbs or deflects the non-Blue wavelengths of light and lets the Blue come straight through.

This is why, when the sun is at a very low angle, the sky appears Red. The Blue light is passing over your head while the Red light is being deflected into your eyes.

Answer 4

This is actually a simple answer. In the color spectrum, blue has the shortest color span. Our eyes pick up the shorter color spans first. That's why the water and sky appear to be blue, but in reality, it has no color.

Answer 6

Yeah, chromatically, certain colors of light are reflected by the atmosphere and other colors are absorbed. Can you tell which ones are reflected?

Answer 7

because of the way the light from the sun bends when passing through the atmosphere
