Sandbridge sunset, taken by my dad August 20, 2012
Sunsets baffle me. My favorite part about living in Virginia Beach, VA is that I live on the bay and walk in the opposite direction not even half a mile and land on the beach. I’m lucky enough to get incredible photo shots of the sun rising in the East over the ocean and setting in the West over my backyard. I understand that a sunset occurs when the sun goes below greater than 180 degrees azimuth. What I am most interested in is the variations in color and how we can often see great colors and views, even after the Sun has set below the horizon.
How does this relate to axial tilt and why do we see some rays of sunlight longer than others? To me, it would seem as though we would see a distinct pattern, but sunsets appear to be randomly casted and colored in the sky. The sun appears to be a bright yellow color; why is it sometimes dark red when it sets, setting off fiery reds and oranges in the sky (see picture above!), and at other times a deep, mellow orange that shows purples and blues?
I’d love to get some more answers on this, and even though it isn’t so scientific in its composition, I can’t help but wonder what it is that causes such great variation in the appearance of a sunset.
