why sky is blue?

Question

why sky is 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

The sunlight interacting with the Earth's atmosphere makes the sky blue. In outer space the astronauts see blackness because outer space has no atmosphere. Sunlight consist of light waves of varying wavelengths, each of which is seen different color. The minute particles of matter and molecules of air in the atmosphere intercept and scatter the white light of the sun. A large portion of the blue color in white light is scattered, more so than any other color because the blue wavelengths are the shortest. When the size of atmospheric particles are smaller than the wavelength of the colors, selective scattering occurs --- the particles only scatter one color and the atmosphere will appear to be blue. Blue wavelengths especially are affected, bouncing off the air particles to become visible. This is why the sun looks yellow (yellow equals white minus blue). At sunset, the sky changes color because as the sun drops to the horizon, sunlight has more atmosphere to pass through and lose more of its blue wavelengths. The orange and red, having the longer wavelengths and making up more of sunlight at this distance, are most likely to be scattered by the air particles.

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.

Answer 4

The sky is blue ......because we pray that our dreams will always come true,
The sky is grey when heartache comes our way,
The sky is white when little angels are in flight!

Sorry I am just in a good mood and felt like sharing it with you!!!!!
have a lovely day Dody!

Answer 5

the blue colour of the sky is because of Rayleigh scattering. As mild strikes by the ambience, maximum of the longer wavelengths bypass instantly by. Little of the purple, orange and yellow mild is bothered by the air. notwithstanding, most of the shorter wavelength mild is absorbed by using the gasoline molecules. The absorbed blue mild is then radiated in diverse guidelines. It receives scattered all around the sky. Whichever direction you look, a number of this scattered blue mild reaches you. because you word the blue mild from everywhere overhead, the sky seems blue.

Answer 6

The sky isn't blue, it is neutral. Your eyes see is as blue because they are on a special wavelength. They also seed red things as red.

Answer 7

its actually a mirror and its the reflection of the oceans that make em' blue

Answer 8

because it looks like its gonna be a nice day. Susie

Answer 9

lite refracted from the nitrogen in the air.

Answer 10

it's all because of the nature..
