Why? The explanation has to do with physics. I am
science-challenged and don’t really fully understand the concept, but it goes
something like this: The blue and violet colors in the sky’s color palette are
short wavelengths, while red, orange and yellow are long wavelengths. As the
earth turns, the wavelengths must travel farther to reach the same spot. The short
wavelengths aren’t strong enough to travel that far through particles, such as
nitrogen, oxygen and dust, in the earth’s atmosphere. So they’re blocked out, and only the long
wavelengths make it through. Clouds and the desert also have a hand in helping
Mother Nature create these spectacular light shows.
Do we really need to understand the science behind
Arizona’s gorgeous sunsets to appreciate them? Not really. All we need to do
is enjoy them!
