why is the sky blue?

Answer 1

is is a property of light called scattering,

at the wavelength that produces blue, photons hit and bounce off of nitrogen.

the light coming from the sun is white, not orange/yellow/red

those colors do not scatter, as they are too wide to hit the atoms. but bluee does hit it. so that leaves the yellowish sun color to travel directly to our eyes, and the blu to fill the sky

Answer 2

As you may already know, we can only see a certain part of the Sun's radiation spectrum, called a visible spectrum. It consists of photons that have wavelengths roughly between 400 and 700 nanometers. Light that has lower wavelength has more energy and is closer to violet.

As the light enters our atmosphere, it starts to scatter because of the air. The light that has more energy (blue, violet, ultraviolet) scatters more intensively and so all the sky seems to be glowing with blue colors.

And when you see the Sun going down near the horizon, you can see red colors only, because in this position you see the light that has already passed through a thick layer of air and all the blue light has scattered away, leaving only the high-wavelength parts that scatter less intensively.

Answer 3

Nearly there, the champagne is on ice. You are person number 1498 to ask the same question. If you don't believe me, type "Why is the sky blue" into the Search for Questions box above. Only two to go for the big 1500 celebration.

The answer, as has been pointed out in most of the previous 1497 sets of answers, is rayleigh scattering. If you look at some of the previous sets of answers, you will learn all about it.

Answer 4

OUr Globe gets illuminated by the light energy given by the Sun. This light energy travels thru space in the form of radiation.As it enter our atmosphere the composite light passes though the atmosphere where the particles in the atmosphere selectively scatter the wavelength corresponding to blue colour that is present in the composite light "Pack" and that is why the sky looks blue.

Answer 5

Light coming from the sun is what's called "white light" White light contains all the colors of the rainbow. When it enters Earth's atmosphere this light is separated into its individual colors by chemical elements in the atmosphere and scattered across the sky. Nitrogen is the most abundant element in our atmosphere, and that element scatters the color blue across our sky more than the other colors. In space, there is no atmosphere to separate colors from the white light and space looks black.

Answer 6

because of the dispersion of the blue color of the spectrum in the clouds..... high intensity light is reflected and low intensity cannot reached in our land.... blue color is the only one left

Answer 7

the sky is blue because of the color oxygen bounces back............it is oxygen that gives it blue color though nitrogen is more abundant in the earth's athmosphere

Answer 8

because the deep of it
As it is high so layer of air will be shown blue like water

Answer 9

Sunlight, air and moisture gives us the illusion of it being blue.
