is the sky reaally blue?

Answer 1

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 2

Not always, it isn't. I have been a landscape painter for about eight years now. The sky is bluer straight above you and more muted and light towards the horizon. However, the sky almost always has a warm tone in it, like red (and sometimes yellow). Thus it is closer to a light tint of blue-violet than straight blue. In fact, the sure sign of amateur painting is if they use unmodulated blue for the sky. The way I mix colors for the sky is Cerulean blue and a touch of Winsor Orange (and some white).

The truth is, the color of the sky changes throughout the day.

Answer 3

WHY IS THE SKY BLUE?
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 4

The sky is blue is an optical illusion. Serenity describes the physics of it well. We PERCEIVE the the sky to be blue as the earth revolves. For instance, we perceive and see the rainbow as an arc, but if we looked at it from outerspace. The rainbow is actually a complete halo, which makes logical, physical sense. It's all in the brain and wavelengths. (We can't see the single, rapid beats that creates images on our t.v. either, but this is how it works.)

Answer 5

Yes. Both the sky and the ocean are blue (although sometimes the ocean is blue-green) because of white sunlight which is scattered from the millions of molecules.

Answer 6

"Sky" does not exist. It is a word that describes a region above the Earth which seems blue but in reality, is an optical illusion. Therefore, it cannot be a color.

Answer 7

yes it is.
lots of people think that the sky is blue cuz it reflects from the ocean but it is really the other way around.( The sky reflects it's blue color onto the ocean.)
hope this helps! :)

Answer 8

No. It just looks blue.

Answer 9

Sometimes,but for the largest percentage of time, it is black with little white polka-dots.

Answer 10

yes it is really blue
