We often see the sun casting red/orange on clouds at sunset. Finally captured it. November 6.
When a beam of sunlight strikes a molecule in the atmosphere, what’s called “scattering” occurs, sending some of the light’s wavelengths off in different directions…
…at sunset, the light takes a much longer path through the atmosphere to your eye than it did at noon, when the sun was right overhead. And that is enough to make a big difference as far as our human eyes are concerned. It means that much of the blue has scattered out long before the light reaches us.
