why the sky is blue?

Answer 1

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.

Answer 2

The answer is simply this. Our atmosphere has a certain composition, which is primarily nitrogen. Thus, our atmosphere scatters the light from our sun in such a way that only certain wavelengths scatter throughout the sky. We see the sky as blue (and not violet, which is also on that end of the spectrum) because our eyes detect blue more readily than violet. The sky and the sun are more red during sunrises/sunsets because there is more atmosphere for the sun's light to get through, so only the long wavelengths (red) can make it through.

Answer 3

The sky is blue because the light passing through the sky reflects the particles in water at a particular wavelength, which is for most days blue

Answer 4

As quoted from this website

"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 5

Because as light hits the atmosphere it breaks from white into the visable spectrum (roygbiv..red, orange, yellow, green, blue, indigo, violet) and blue happens to bend the most making it more of what you see out of the light that hits earth

Answer 6

yes, it's the reflection of the water. I think I'm gonna go to the tap and pour out some blue water right about now. water's always blue. it certainly isnt colorless like some people say. those people are just crazy.

Answer 7

Sky is not blue in reality. it just looks blue from earth

Answer 8

something to do with the frequency of light as it passes thru the atmoshere.

Answer 9

that's the question everyone's been asking for timeless years

Answer 10

because of the reflection from the water creates this otherwise it would be black or gray.
