The sky appears blue because sunlight, which contains all colors of the rainbow, is scattered by gas molecules in Earth's atmosphere; shorter blue light waves scatter more easily than longer red and yellow waves, filling the sky with blue light that our eyes detect from every direction.

“Why Is the Sky Blue? 🌈 The Real Reason Will Surprise You 😳”Añadido:
You stand in an open field at noon, looking directly up at the blinding [music] white disc of the Sunday. It seems simple, but that light is a hidden spectrum.
You hold a glass prism as it passes through. It fans out into a vibrant rainbow of red, orange, and violet. This [music] is the secret ingredient of the sky.
As sunlight hits the Earth, it slams into gas molecules. Think of these particles like tiny pinball bumpers waiting [music] for the light to strike.
The red and yellow waves are long and lazy, passing through untouched. But, the blue light waves are short and energetic. They collide and scatter in every direction.
>> [music] >> Every time you look up, your eyes catch that scattered blue light coming from every corner. It is a constant, [music] brilliant explosion of color happening right above your head. Now, watch the horizon as the sun begins to dip. The light travels a longer path, scattering the blue away, >> [music] >> and leaving only the stubborn red and orange waves to paint the clouds.
The sky is not a solid color.
It is a giant [music] shifting game of light and physics playing out forever.
