Physics of morning golden lights (Patreon)

Rayleigh scattering is a phenomenon in which short-wavelength light particles, such as blue and violet, scatter more intensely in all directions.

In comparison to short-wavelength light, long-wavelength particles like red and orange scatter less.

Therefore, during the evening or morning light, when the sun's rays pass through a thicker layer of the atmosphere, it can acquire a golden hue due to this uneven scattering.
