Why does the sky appear blue?

Answer 1

light is reflected and refracted as it enters the atmosphere leaving only the blue part of the spectrum visible

Answer 2

I've always wondered about those people who think the sky is reflecting the ocean. Does the ocean turn red at sunset? Is the sky yellow in Oklahoma, so far from the water? If the sky reflects, why can we see things like the Sun and Moon through it? Heck, you can even see Venus during the day, if you know where to look.

It's called Rayleigh scattering, and it has to do with the bending of light by air. When the Sun is near overhead, there's not much air to pass through, so only the shortest wavelengths get bent. When the Sun is near the horizon, its light is passing through so much more air, and even the longer red waves are refracted. That's also why the sky is redder at sunset when it's cloudy and the air is filled with water.

Answer 4

that's due the scattering of sunshine by potential of the ambience; the quantity of sunshine scattered by potential of the ambience is inversely proportional to the 4th potential of the wavelength of the mild; Violet and Indigo, however having very small wavelengths, are no longer straight forward colorings; they are compound colorings; So, they are no longer scattered; next to Indigo is Blue, that's an straight forward shade; So, that's scattered profusely by potential of the ambience; And, the Sky seems Blue;

Answer 5

I think it's because miniscule molecules of water that are always in the air. Sun light reflects like prisims off the water droplets and reflects the color of the water vapors otherwise unseen.

Answer 6

Is the sky blue? I hadn't noticed.

Answer 7

the sun reflects the appearance of the water since it takes up 3/4's of our planet

Answer 8

Because the ocean is blue and it reflects from there.

Answer 9

This has to do with the scattering of light in oxygen.
