why is the sky blue?

Answer 1

When the light from the sun enters the atmosphere it interacts with particles that seperate out the light (like a prism) in such a way that blue is the color we see. The sky is more of a rainbow color during sunrise & sunset because it enters at a different angle.

Answer 2

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the visible spectrum). Therefore the light scattered down to the earth at a large angle with respect to the direction of the sun's light is predominantly in the blue end of the spectrum.

Answer 3

The different wavelengths of sunlight are scattered by molecules and dust particles in the atmosphere, but the colours of the visible spectrum don't scatter in equal proportions.Blue has a shorter wavelength and scatters more readily than the longer
wavelenghths of red and orange. So what you're actually seeing is indirect, scattered light making the sky appear blue.

You were a bit hasty asking the question today. If you type "why is the sky blue" into the Search for Questions box above, you will see that the question has now been asked 1489 times. In about two days, asker number 1500 will log in and the champagne corks will fly - every one aimed directly at the head of asker number 1500.

Answer 5

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Answer 6

Due to the atmosphere being made up of Hydrogen, Nitrogen, Helium & Oxygen, the colour is a side effect, I beleive if you were to juggle it around abit you could get purple, how funky yet completely freaked out would that be. If you have ever flown over some of the big citys you mya have seen smog in the summer, theres a good example

Answer 7

Its the light refracting through the water particles in the sky

Answer 8

It's not always blue, also the secret no one knows is... its because blue is the colour of everything when it is far away and the sky is very far away...

Answer 9

Rayleigh scattering. Just like it was the last 100 times this was asked today.

Answer 10

Something about light refracting the shortest wavelength.
