Sunset with sky colors due to the diffusion or scattering of light, radiation-matter interaction. High-frequency scattering for indigo (short wavelength), low-frequency scattering for orange (long wavelength).
Summary
[edit]
| Description |
Italiano: I colori del cielo al tramonto originano dal fenomeno della diffusione o scattering di Rayleigh della luce solare, sorgente incoerente e naturale, da parte delle molecole dell’atmosfera terrestre (interazione radiazione-materia). Le lunghezze d’onda corte (violetto/blu) vengono diffuse più intensamente per scattering ad alta frequenza, rendendo il cielo azzurro durante il giorno. Al tramonto, la luce attraversa uno strato più spesso di atmosfera: le lunghezze d’onda corte vengono disperse e prevalgono le lunghezze d’onda lunghe (rosso/arancione) come scattering a bassa frequenza, che conferiscono al cielo i colori caldi tipici.
English: The colors of the sky at sunset arise from the phenomenon of Rayleigh scattering of sunlight, an incoherent and natural source, by molecules in the Earth's atmosphere (radiation-matter interaction). Short wavelengths (violet/blue) are scattered more intensely by high-frequency scattering, making the sky blue during the day. At sunset, the light passes through a thicker layer of atmosphere: the short wavelengths are scattered, and long wavelengths (red/orange) prevail as low-frequency scattering, giving the sky its characteristic warm colors. |
