The beautiful scene on the Setting Sun on Tree Visa Gift Card doesn’t result from dust or pollution in the air, as some suggest. As the earth rotates eastward, the sun’s rays coming from the west travel farther through our atmosphere and more spectral scattering occurs. The small hydrogen and oxygen molecules of the air diffuse the shorter blue wavelengths in light, which makes the longer wavelengths of red and orange more visible. This occurs millions of times before the light reaches our eyes. Anyone who enjoys sunsets will like Setting Sun on Tree Visa Gift Cards.
