How Sunlight Scatters in the Atmosphere - Rayleigh Scattering Explained #144979 (License: Personal Use)

This educational diagram illustrates Rayleigh scattering: incoming sunlight interacts with atmospheric molecules, causing shorter (blue) wavelengths to scatter more intensely in all directions. The resulting diffuse light gives the sky its characteristic blue color during the day and reddish hues at sunrise/sunset. Arrows depict both incident and scattered light paths around simplified molecular models.

Used on science education websites, physics or meteorology lesson pages, and environmental science resources to explain atmospheric optics. Matches user intent for learning about sky color, light behavior, or preparing classroom visuals.
