Why is the sky blue?

Question

Is it blue and grey because the sea is and the skys mirrored or is it when the ocean evaporates intot he heated air it evaporates the dye from the water into it and that is what makes water clear?

Answer 1

Shorter wavelengths corresponding to blue light are scattered much more than longer wavelengths of light, so blue is the predominant color. For this same reason the moon turns a shade of red during a lunar eclipse, since the little bit of sunlight hitting the moon first travels through the earth's atmosphere, filtering out the shorter wavelengths and resulting in a reddish hue.

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

When light passes through a clear fluid holding small particles in suspension, the shorter blue wavelengths are scattered more strongly than the red. This can be demonstrated by shining a beam of white light through a tank of water with a little milk or soap mixed in. From the side, the beam can be seen by the blue light it scatters; but the light seen directly from the end is reddened after it has passed through the tank.

This is called the Tyndall effect, but it is also known to physicists as Rayleigh scattering.For his conclusive studies that blue light is scattered more than red light by a factor of (700/400)4 ~= 10.

Answer 4

Neither, interesting as the ideas are. The sky is blue because of the scattering of light by the air molecules (oxygen and notrogen molecules mostly). Since the scattering of light is linked to the wavelength (shorter wavelengths are scattered more), blue light is scattered more and hence sky looks blue.

Answer 5

the sky is blue because 3/4th of the Earth "is" oceanic water that mirrors the atmosphere on a cloud-free and sunny day. And the other reason is located right "inside your heavenly body, of all {heavenlybodies} ever studied by a collective group of scientist of any profession. Amazing is'nt it?

Answer 6

I think the sky is blue, b'cuzz God made it dat way.

Answer 7

The short answer is because air is blue.
