Blue skies are always beautiful to look at, but at dusk and dawn, why are oranges or golden purples so much more radiant?
Who doesn't love a twilight sky? Sometimes the light shines in golden orange and red with a unique purple-purple gradient.
In fact, this color is often seen in the morning, at dawn at sunrise. So, what determines the color of the sky, when does the sun rise or set?
Sunset colors result from a phenomenon known as shining light. The small molecules and particles in the atmosphere change the direction of the light rays, causing them to scatter or scatter in the air.
Scattering affects the color of light coming from the sky, but the details are determined by the wavelength of the light and the size of the particles. Short waves of blue and purple light are scattered by molecules in the air across the spectrum.
This is why blue and purple light reaches our eyes from all directions when the weather is clear.
However, because our eyes can't see violets very well, the sky appears blue.
"Because the sun is low on the horizon, sunlight passes through more of the air as the sun sets and rises in the morning"
More atmosphere means more molecules scattering purple and blue light from the eye.
If the wave was long enough, all the blue and purple light would disappear from view.
"Other colors continue to attract attention. This is why sunsets are often yellow, orange, even red."
In addition, because red has the longest wavelength of all visible light, the sun turns red when it is right on the horizon.
"Where its very long trajectory through the atmosphere blocks all other colors."
