{wiki=Shadow_bands}
Shadow bands are thin, wavy lines that can sometimes be observed on the ground or on surfaces during a solar eclipse, particularly just before and after totality. They occur due to the diffraction of light around the edges of objects, such as leaves or other irregularities in the environment. As the sunlight becomes partially obscured by the moon, the varying light levels and angles create these patterns that move rapidly across surfaces.
