why the sky is blue?

Answer 1

http://www.answers.com/rayleigh%20scattering

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 2

Only people with blue eyes see the sky as blue. People with brown eyes see the sky as brown. Albinos can see stars during the day time because to them the sky is clear.

Answer 3

look, there's no god
the sky is blue because we live in a ******* marble

the universe.. yeah, ok, what's beyond that? The edge of the "marble" It's round, obviously, so I'm calling it a marble. We're basically nothing compared to the rest of the world. The world includes what we don't know, so categorizing it with an English word is proper.

Answer 4

for the same reasons that are listed twice a day on this board. That means over fifty times at least. You know, we are not being rude to point that out to you because when you wrote that question and submitted it, Yahoo told you that there had been exactly the same or similar answers. Can't you type the question into google and get an aswer or finish sixth grade science and get an answer? Nothing personal, but you were told it was a similar question.

Answer 5

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 6

The color blue was named after the color of the sky, so by definition the sky, when blue, is in it's most common configuration from your standpoint. But at night, it's not blue. Guess what color was inspired by the night sky?

Answer 7

It must be sad.

It had a stromie relationship with clouds a few days ealier?

If light doesn't shine on the sky is it still blue?

Because you have to look up to see it the red blood flows down and we all know that white minus red equals bule.

Answer 8

Because there is: [(Άζωτο) 'azoto] - Most of the Air you breathe is NITROGEN, #7 in the periodic table -> 'N' nitrogen is a gas in the atmosphere in high consentrations about (60-70%).

Nitrogen absorbs the harmful high energy infrared wavelengths and reflects a blueish cool color (Its giving off more than blue, but it can't be seen because its not inside the spectrum of the visible light wavelengths).

Answer 9

the sky is blue because of the reflection of the rainbow

Answer 10

it just looks blue.... its looks blue because the light from the sun reflects through Hydrogen molecules, making the sky look blue.
