atmospheric scattering
Atmospheric scattering is the process where light from the sun interacts with the particles and gases in the Earth's atmosphere. When sunlight passes through the air, shorter wavelengths, like blue and violet, scatter more than longer wavelengths, like red. This scattering causes the sky to appear blue during the day. At sunrise and sunset, the sun's light travels through more atmosphere, scattering the shorter colors and leaving the reds and oranges, which is why we see those vibrant colors during those times. This phenomenon plays a significant role in our daily visual experience of the sky.

Atmospheric scattering refers to the way sunlight interacts with tiny particles and gases in the Earth’s atmosphere. When sunlight hits these particles, it gets redirected in different directions. This scattering causes phenomena like blue skies—shorter blue wavelengths scatter more than longer red wavelengths. During sunrise and sunset, the light path is longer, scattering out the blue and allowing warmer colors to dominate. Essentially, atmospheric scattering affects how we perceive the color of the sky and can create beautiful effects during different times of the day.
