Why is the sky blue? The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more...
What's the scientific reason behind Earth's sky appearing blue to the human eye? And what's the real colour of the sky?
Feb 11, 2024 · The sky’s blueness primarily comes from a phenomenon called Rayleigh scattering. When sunlight interacts with the Earth’s atmosphere, the shorter blue wavelengths of light are scattered more than the longer red wavelengths.

If you've ever wondered why, like Irving Berlin, you see \"nothing but blue skies,\" you're in good company. It took many centuries and a lot of smart people -- including Aristotle, Isaac Newton, Thomas Young, James Clerk Maxwell and Hermann von Helmholtz -- to puzzle out the answer, in part because the solution encompasses so many components: the ...
Let's take the sky out of the equation for a moment and begin by looking at color. From a physics standpoint, color refers to the wavelengths of visible light leaving an object and striking a sensor, such as a human eye. These wavelengths might be reflected, or scattered, from an external source, or they might emanate from the object itself.
The color of an object changes depending on the colors contained in the light source; for example, red paint, viewed under blue light, looks black. Isaac Newton demonstrated with a prism that the white light of the sun contains all colors of the visible spectrum, so all colors are possible in sunlight. In school, most of us learned that a banana ap...
