Sunset in a village called Quatretonda

This photo was taken by Aina Pons on April, 8 2020 in Quatretonda (Valencia, Spain), at a latitude of 38° N and a longitude of 0.5°W. In this picture we can observe the typical reddish colors produced by the Rayleigh scattering. This effect is based on the strong dependence of the Rayleigh scattering with respect to the light wavelength: shorter wavelengths scatter much more than larger ones, and therefore at sunrises and sunsets – where the Sun is near the horizon- the light paths are larger, thus scattering out almost all of the bluish colors.
