Why is the sky blue

Why is the sky blue?

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 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 the light from our Sun shines into the atmosphere most of the colors are able to reach the Earth’s surface uninterrupted. However, because blue light has a wavelength that is the same size as the particulates in the air, this light is scattered in every direction. This blue light bounces from particulate to particulate until it eventually reaches your eyes. For this reason, no matter what direction you look in the sky, it appears to be blue. This blue light originated with the Sun, was bounced around in the sky many times, and then eventually reached your eyes.

The true, metaphysical reason is:

♪Planet Earth is blue.♪
♫And there's nothing I can do.♫

its not, are you crazy! on a sunny day, the sky is bright green and purple. when it rains, it is a very deep yellowish red

The Sky is actually Black the Blue Ocean shines on the Sky tht makes The Sky Blue during the Day

The sky is blue cuz the light of the sun reflects the color of the seas and oceans.

I hate when people ask this question.

why are there stereotypes

Because of our Earths atmosphere
