Characteristics of sunset:

Sunset refers to the sun in the evening and also refers to the west of the mountain. Sunset is usually orange-red because it is close to dusk. The formation principle of sunset glow and sunset glow is slightly different. Astronomers have long discovered that the earth's atmosphere will scatter light.

187 1 year, British scientist Rayleigh proved that the scattering of short-wave light is much stronger than that of long-wave light. Therefore, tiny dust and air molecules in the atmosphere scatter short-wave light (purple light) in sunlight more than long-wave light (red light) 10 times. From here, we can also know why the sky is always blue, because the sun shines through at sunset and sunrise.
