why is the sky blue?

Answer 1

It's not, why did you think it was?

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.

Blue sky from scattered light

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 4

ok, short science lesson here:

The sky is blue because:

Blue light gets scattered (spread) around much more than all the other colors from the sun, causing the sky to appear blue.

The Long version is:

Light is made up of electromagnetic waves.

The distance between 2 crests in this wave is called the wavelength.

White light contains all the colors of the rainbow.

The amount of light scattered for any given colour depends on the wavelength of that colour.

All the colors in white light have different wavelengths.

Red light has the longest wavelength.

The wavelength of blue light is about half that of red light.

This difference in wavelength causes blue light to be scattered nearly ten times more than red light. Lord Rayleigh studied this phenomena in detail. It is caused the Tyndall effect or Rayleigh scattering.

Answer 5

The sky is blue because air scatters short-wavelength light in preference to longer wavelengths. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead

Answer 6

The sky is blue because the gasses that make up our atmosphere reflect the blue portion of the visible light back to the ground, and that's what our eyes see.

Answer 7

It actually has nothing to do with reflection of bodies off water, and everything to do with the light spectrum.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight. The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 8

because of the way the the suns light particles are reflected through the matter that makes up the sky

Answer 9

My sorces tell me that the sky is blue because of the oceans reflection.

Sun light reflecting off of bodies of water, mainly the ocean
