What refracts blue light to make the sky blue?

Answer 1

"The sky is blue because, the universe is black and when you flash the sun on it it turns blue, so there u go"-Dan

That is part true. The colors of the rainbow go at different speeds. Blue is the slowest of all colors and gets caught by many things before it reaches your eyes. The layer of ozone in the earth's atmosphere (Ozone Layer) catches some of the blue light and keeps it in the sky. The rest is let down onto the seas, to make the water look blue.

Answer 2

If you went into outerspace, it would be a blackness. Since Earth has so many layers separating the Earth's surface and outer space, in every layer, the color get lighter. So that makes the sky we see a light blue.

Answer 3

WHY IS THE SKY BLUE?

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 during sensets.

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.

WHY IS THE SUNSET RED?

As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes.

The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.

Answer 4

It's more that the atmosphere scatters blue light more readily than it scatters red light. That portion of the scattered light that reaches your eye therefore contains more blue than red, yellow, etc, so the sky looks blue.

Answer 5

The Earth's atmosphere scatters blue light from the sun in all directions, making the sky appear blue. This scattering is known as Rayleigh scattering, where shorter blue wavelengths are scattered more than longer wavelengths like red. As a result, blue light is redirected in different directions and becomes visible to us, creating the sky's blue color.

Answer 6

light scatters and the human eye sees the color blue more than any other color

Answer 7

Yes, it is true that blue light scatters more effectively than red light, so that white light from the sun scatters in such a way as to make the sky appear blue.
