why is the sky blue?

Question

I want to know cause everyone has been tellin me different answers!!!

Answer 1

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 2

like the obove guy said, as you might know lenses, prisms and water droplets break up the light in different colours by bending it a little.

the earth is a globe surrounded by gasses. which acts like a lens.
it splits the colours and bends them. it just so happens that blue is directed towards the earth, red is refracted much higher in the sky.

note: that is why a sunset is red/orangy. and the sky around the sun in daylight seems yellowish.

ps. the oceans are blue because the sky is blue. they reflect like a mirror. oceans sometimes are gray when its cloudy.

Answer 3

The atmosphere scatters light particles, red light particles and blue light particles. When the sun is above, it passes through the least amount of atmosphere at the angle you see it. This makes the sky blue. When the sun is setting, the angle you are seeing the light makes the light travel through more of the atmosphere, and you see red light.

Answer 4

It is what your retinas interperate the color as. The sky is blue mainly because of the atmosphere. The different gases that make up our atmosphere reacts with the sunlight in a way that when it is lit up in the day time, it appears blue. Notice that when there is NO sunlight...like at night, you cant see it at all. you just see straight into space.

Answer 5

When light comes through our atmosphere, it bends, and we see the blue wavelenghth. My answer may be a little skiewed but I can reassure you it has nothing to do with the oceans or the fact that water vapor is present in our air.

Answer 6

Our atmosphere so mostly nitrogen. An (N) defuses blue light.
And that is why at the end of the day the sun has more atmosphere to go through. That defuses more blue and you have yellow and red left.

Answer 8

I asked my ex bf once *&* he said cuz he told it to be... Lmao! Buh I Really Dont now why.. tell me when ya find out

Answer 9

because god made the sky blue

Answer 10

BECAUSE MOLECULES IN THE AIR SCATTER BLUE LIGHT FROM THE SUN MORE THAN THEY SCATTER RED LIGHT.
