Question

Why is the sky blue? Is it because of the water reflecting on it and making it blue?

Answer 1

Here ya go. A very simple answer.

Answer 2

Yes. 'Cos when the sky's cloudy, the sea's not blue, usually grey, etc.

Answer 3

Yep!...at least that's what I heard...lol!♥

Answer 4

The sky is blue because as visible light passes through the atmosphere the blue part of the spectrum is bent the most because of the air and water molecules in the atmosphere. Any one who says that blue light is absorbed and then radiated doesn't know what they are saying.

Answer 5

I'm appaled at the though that so many people think that water makes sky blue. What about blue skies over the land which is thousands of miles away from sea?

No, my dears. The sky is blue because the blue part of the sun's light is scattered by our atmosphere more than any other colour. Now go back to your class.

Answer 6

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 7

This question has been asked several hindered times and it must have come up when you set up your question, so why on earth did you post it. The answer is

RAYLEIGH SCATTERING..

Answer 8

No it is not water reflection...

Because light from the sun is scattering by atoms and molecules in the atmosphere.

Light scattering by particles depends on the relative "sizes" of the photons and the particles.

In the case of visible light, molecules are much smaller than the wavelength of light, so blue light gets scattered much more than red light.

So as light from the sun enters the atmosphere, more blue photons get reflected (not absorbed) by molecules than red photons - but then the blue photons get reflected again and again until they reach us. So the blue light comes from all over, the red light comes almost straight from the sun.

This is also why the sun looks redder at sunrise and sunset - the light's path through the atmosphere is longer when the sun is on the horizon than when it is high in the sky.

Interaction of light with the atmosphere does all sorts of weird and wonderful things that physics can explain:

Or look at the many times this question has been asked before by searching for your question – I think it has been asked over 8000 times

Answer 9

OMG this has been asked about a billion times on here, who cares!

Answer 10

The sky and water are blue for the same reason.

Blue has a short wavelength and scatters easy so it seems more predominant.

Answer 11

By george I think you have got it!

Answer 12

No its something to do with blue being the last colour our eyes can see.
