why is the sky blue?

Answer 1

Blue light scatters more than red light off the atmosphere. So when you look at the sky perpendicular to the sun, it looks very blue. When you look at light which goes through a lot of atmosphere without scattering (as you do at sunset), the sky is very red.

Check out the wiki article on Rayleigh scattering--to read more and get links if you really, really want to know why the sky is blue.

Answer 2

Tyndall Effect
The first steps towards correctly explaining the colour of the sky were taken by John Tyndall in 1859. He discovered that 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. The scattered light can also be shown to be polarised using a filter of polarised light, just as the sky appears a deeper blue through polaroid sun glasses.

Answer 3

um, well some are somewhat right from what i know , the atmosphere is filled with particles of dust and the light is refracted through and is seperated in many spectrums mainly the blue, i dont believe that its a reflection of the ocean my answer is dust particles make the sky blue

Answer 4

sunlight bounces off particles in the atmosphere so they twist and are dispersed as a certain wavelength. Our eyes perceive this wavelength as BLUE. When the sun sets there is a different angle, different angle of twisting, so different wavelength. THis is why the sky is red at sunset, and blue in the day.

Answer 5

for your changing emotions,
they are the clouds,
and the sky in its beauty
is more than blue... it is you

just remember that storm's pass
as the night turns to day
you will always be the sky
and the stars will lead your way

Answer 6

Oxygen in the air (air is approx 20 % Oxygen) has a blue color. The reason for its blue color is due to its absorption of light in the visible spectrum - reason to detailed to give here.

Nitrogen (approx 80% of the air) has no color.

Answer 7

I know there is a correct answer to that, but I forgot it. I think its in a 5th grade science book. Something to do with the reflection of the ocean...but I don't remember. (I'm not smarter than a 5th grader...LOL).

Answer 8

coz of raman's scattering

Answer 9

the color pigments in the air or something lyk that........in my opinion b/c the grass is green! lol

Answer 10

It's not. It's orange. How long have you had this?
