hi...

the answer is simple...

we feel the sky is blue because of a phenomenon called scattering of light OR RATHER IT IS KNOWN AS RAYLEIGH SCATTERING... light passes thorough the watermolecules and gets scattered... so the colours of longer wave length gets absorbed and with those of shorter wavelength is seen i.e the blue colour 's wavelength is short(VIBGYOR)..that is why the sky is blue and the ocean is green

OK, here's an attempt at an answer without physics:

I think most people know that sunlight is made up of light of several different wavelengths, and can be split up into the colours of the rainbow. Blue light has the shorter wavelength, and red the longest wavelength.

When sunlight hits the molecules in the atmosphere, the light gets bounced around by the molecules (what actually happens is that the light strikes the molecules and is absorbed, causing the molecules to vibrate and give off, or 're--emit' the lightt; but 'bounce around' is close enough).

Because the blue wavelength is shorter and more energetic, it reacts much more with the air molecules than the red and yellow wavelengths; which tend to pass straight through. Because the blue radiation is re-emitted from the air molecules in all directions ('scattered'), it seems to us looking from the ground that the blue light is coming from everywhere; hence the sky seems blue.

Near sunset, because of the low angle of the sunlight, we see more of the red and yellow wavelendth passing straight through, hence the colours of the setting sun.

BTW: The sky isn't blue because of a reflection of the sea; its the other way round, although water molecules can also scatter the blue light, which gives the intense blue colour to ice, if we look down a crevasse in a glacier.

The sky is blue because when the sun reflects off of the bodies of water the earth contains it also reflects the shades of blue that the water portrays.

there are several fields in the electromagnetic radiation we recieve from the sun.one field is the visible light field which consist of 7 basic color of light. everything has color u can see(plants,rocks,...etc)absorb all the color of the visible light but reflects only one color this is what u can see.
