Is the sunset glow on the pavilion a scattering of light?

The sunset glow in the pavilion is the scattering of light.

The sun falls below the horizon, and the red, orange and yellow light with longer wavelength in the sun refracts into the air. When it meets water droplets and dust composed of water molecules in the air, it will scatter, making suspended particles that do not emit light turn into colorless light sources because of scattered light. When these rays enter human eyes, they will see colorful sunset clouds.

The formation of sunset glow is due to the scattering of light by air. When sunlight enters the atmosphere, it will scatter when it meets atmospheric molecules and particles suspended in the atmosphere. These atmospheric molecules and particles themselves do not emit light, but because they scatter sunlight, each atmospheric molecule forms a scattered light source.

Correlation principle:

According to Rayleigh scattering law, light with shorter wavelength such as violet, blue and cyan in the solar spectrum is most easily scattered, while light with longer wavelength such as red, orange and yellow has stronger light transmission ability. So we see that the clear sky is always blue, while the light above the horizon is only yellow, orange and red with longer wavelengths. After these rays are scattered by impurities such as air molecules and water vapor, the sky there will be colorful.

As the saying goes, "Don't go out at sunrise, but go to Wan Li Road at sunset." In other words, the bright red light in the morning shows that there are many water droplets in the atmosphere, which indicates that the weather is going to turn rainy. If there is a fiery red or golden sunset glow, it means that there is no cloud in the west, and the sunlight can be transmitted to form a sunset glow, which indicates that the weather will be fine. Colorful clouds sometimes appear on the horizon around sunrise and sunset. The chardonnay seen in the eastern sky around sunrise is called morning chardonnay, and the chardonnay around sunset is called sunset chardonnay.
