why is the sky blue?

Question

???????????

Answer 1

Because of the refraction of light
The molecules in our atmosphere absorb some of the lower frequencies of light, leaving more of the higher frequency lights.
Thereby resulting in a bluish colour.

NEVER let anyone tell you that it is because of the reflection of the ocean.
THAT IS WRONG. IT IS NOT THE REFLECTION OF THE OCEAN.

Thanks.

"The color of the sky is a result of diffuse sky radiation which results in a light blue color"
"Diffuse sky radiation is solar radiation reaching the earth's surface after having been scattered from the direct solar beam by molecules or suspensoids in the atmosphere. Also called skylight, diffuse skylight, or sky radiation. Of the total light removed from the direct solar beam by scattering in the atmosphere (approximately 25 percent of the incident radiation), about two-thirds ultimately reaches the earth as diffuse sky radiation."

Answer 2

The blue color of the sky is due to Rayleigh scattering. 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.

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white. 


Answer 3

When sunlight travels through the atmosphere, blue light scatters in all directions, much more so than the longer wavelength colors associated with yellow and red light. When the blue light scatters to the earth's surface, we can see blue light, but only during the day. At night sunlight does not travel through the atmosphere. Violet light is scattered more than blue, so you might conclude that the sky should be violet. There are two reasons the sky is not purple - there is less violet in the sunlight that reaches us and our eyes are not as sensitive to violet as they are to blue.

Answer 4

Due to the scattering of different wavelengths of light.
As light moves through the atmosphere, most of the longer wavelengths (red, orange and yellow) pass straight through.

However, much of the shorter wavelength light (i.e. BLUE) is absorbed by the gas molecules and then radiated in different directions (i.e. 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 5

Because the earth is surrounded by several layers of atmosphere. The important one here is the ozone, which refracts sunlight as it comes in, and reflects much of it (especially the uv rays) back into space. One of the side effects, is that the wavelength of light for the color blue gets spread off to the sides, while red and green light get left alone. That's why sunlight looks yellow to us (in light, red + green= yellow), and why the rest of the sky looks blue in the day.

Answer 6

What we see as sky is the atmosphere, filled with transparent air and dust particles. In daytime, we have sunlight illuminating the atmosphere. White light is nothing but mixture of lights of all visible colours. Out of them blue light is in one end of the spectrum , having lowest wavelength among visible lights and red light is in the other end of the spectrum , having longest wavelength.An wavelength of light is the distance travelled by a particular colour of light within one cycle of vibration. So during one vibration only a light of longer wavelength perhaps reflected longer, i.e., scattered less.This might be the reason.Dust particles scatter blue light more than red light ( and the inbetween colours in the same order) We see an object only when it scatters light, i.e. reflects light halfhazzardly, and see its colour as the colour of the light most scattered by it. When something reflects light perfectly, we do not see it, as we thing that light comes from behind it, as we perceive light to be travelling in straight lines.Thus we cannot see a mirror, but the image of the object reflected in the mirror.Dust particles everywhere in the atmosphere are collectively seen as 'blue sky'.

Answer 7

Because, the oxygen in the atmosphere absorbs most of the light from th sun, causing only blue to be reflected on earth.

Answer 8

its because we have 70%water which is actually blue
so from top its seems blue

Answer 9

because it reflects the color blue from the water

Answer 10

Love is like Oxygen! You get too much you get too high, not enough and your gonna die, love gets you high.

Is it a reflection of the oceans waters????
