Why the sky is in blue color?Can anyone pls explain?

Answer 1

When light from the sun enters our atmosphere, it interacts with oxygen in the sky. The oxygen particles act as a prism that separate the light into it's different wavelengths (rainbow), but ... oh it's too much to type... here are a few answers to the most commonly asked question on Y! Answers:

Answer 2

The reason, basically, is because air is blue. Weird but true.

That seems wrong, 'cause air is clear, right? Like water is clear. If you look at a glass of water, that's true; but if you look at a whole lot of water, like a lake or an ocean, it looks blue or even green. The same is true of air; "up close" it looks clear, but when you look up in the sky you're looking through miles and miles of air (an ocean of air), and then you can see that it's blue.

More technically: As sunlight passes through the atmosphere, the longer wavelengths (red and yellow) get absorbed, but the blue wavelengths "bounce off" and get scattered throughout the atmosphere. (This is why anything has a color; it absorbs some wavelengths of light and scatters others.)

Answer 3

The sun's rays hit the Earth's atmosphere, where the light is scattered by nitrogen and oxygen molecules in the air. The blue wavelength of this light is affected more than the red and green wavelengths, causing the surrounding air to appear blue. At sunset, the sun's light passes farther through the atmosphere, deflecting and decreasing the blue in the air. Scattering by dust particles and pollution in the air causes the sunset to appear red.

Answer 4

First responder is not correct. Air molecules are comparable in size to the wavelength of light, and particularly of light of shorter wavelengths (blue) so will preferably scatter photons of such wavelength. So, light from the sky is blue, but at sunrise and sunset, the blue light is scattered to the side so the sun appears red. This question regularly appears in this forum, and I wish that people would do a bit of research before asking it yet again.

Answer 5

It's actually not. The sky appears blue to us because of the way that the light reflects off our eyes. That's why under certain lighting the sky can appear a greenish mucky color or even a deep purple.

Answer 6

I think this may be wrong, but I once heard it's blue b/ of the water reflecting on it. I'll check back if someone puts a better answer. I'm curious too.

Answer 7

It's the refraction of sunlight off of the atmosphere.

Answer 8

its a reflection of the oceans
