Why is the sky blue?

Question

When sunlight passes through our atmosphere, the water droplets and other things in the air
diffuse the sunlight. Everything in the air acts like a prism. If you notice the color
spectrum, blue does have the shortest wavelength than red so therefore it does not scatter
or disperse, it comes through and that is what we see. The colors toward the reds have a
longer wavelength and they diffuse or scatter easier than blue, more atmosphere like at
sunrise and sunset gives the reds as the short wavelenghts are bounced away from our eyes.

Answer 1

You may know the answer, but you still make the spamilicious list.

Answer 2

Colors are part of the visible light spectrum. Humans are able to see colors when an object reflects a certain wavelength. This reflection is picked up by the human eye, and is translated into a specific color. So, the sky is blue because the particles in the sky reflect mostly blue wavelengths.

Answer 3

Its because our atmosphere is composed of mostly Nitrogen and this gas scatters more of the blue light from the spectrum than the other colors so our sky looks blue.

Our planet is very rare in the solar system and perhaps the universe as all the other planets would have a black sky even in their daytime. So in theory you would be able to see the stars in the daytime as a black sky would show this.

Answer 4

because blue is the wavelength that humans see the best
