Why is the sky blue?

Question

lol

Answer 1

there are these little particles in the sky, and theyre blue. because there are so many of them, it gives it this effect when we look at the sky.

Answer 2

OK, white light is made up of the spectrum of colours you probably know and love. The sky is made up of atoms and molecules of gas.

When pure sunlight moves through the atmosphere, the short wavelenghts of light (blue) are scattered about by the air molecules. So, any air with light in it is blue.

Aha, but what about sunset... Well, all that scattering is still occuring, but to reach you that light is traveling through a lot more air and all the blue kinda gets scattered out- leaving the longer wavelength light (red) to get to you.

The sky itself isn't really any colour as such, it sort of depends.

But why? you might ask. The sky doesn't need a reason- it just is. The light scattering explanation is a description of how the process occurs. ...I hope this was in fact the answer for which you were looking.

Answer 3

Sir Isaac Newton actually spent more time researching this question than he did for either developing his construction of calculus or on his Laws of Gravity. He did experiments with a prism and found that light coming from the sun consists of many different wave colors, which add up to the white light we perceive. The blue is toward one end of the spectrum; the red are toward the other end. How a particular color is perceived particularly depend upon the angle at which it arrives for our sensory perception - in this case that light that enters the atmosphere at the most oblique angle is what is perceived as blue. Other factors include the medium (i.e., the air of the atmosphere), which in this instance includes a thin layer of ozone in the upper atmosphere, which bends the rays of light a bit further so that we perceive a blue color at our retina.

Answer 4

The particles in the sky reflect blue light as the sun passed through them.
In the color spectrum the longest wave lengths of light are on the red end and the shortest is on the blue violet side

Answer 5

The sky appears blue because air scatters short-wavelength light in preference to longer wavelengths. Since blue and violet have shorter wavelenghts than the reds and yellows they are diffusely scaterred, and make the sky blue.

Answer 6

Raleigh and Mie scattering vary as a high power of frequency. Blue light is scattered most. Shooters wear yellow or orange lenses to filter out short wavelength, high frequency scattered light.

Answer 7

the sky is blue because your eyes see the blue color during the day time with some white spots such as clouds and airplanes
PS-airplanes could be different colors

it is also black becasue your eyes see the black color during night time with some colorful spots such as stars and airplanes

Answer 8

the sky is blue becuz of the atmospheric gases

Answer 9

Actually the sky is black. When you shine light on black (sun) it becomes blue.

Answer 10

I like innocent's answer but arthurkl…sounds more accurate give the best answer to Innocent. in my opinion.
