AI overview

A shadow is a dark area that forms on a surface when an object blocks light from a light source. Shadows matter because they are a visible consequence of how light interacts with objects, and understanding them helps explain everyday optical phenomena we observe around us.

影，又稱影子、陰影，是從光源直射的光被的物體阻擋時形成的深色範圍。當光源置於物體前方時，影會佔據物體背後三維空間的體積。影的截面是一個二維的剪影，是物體阻擋光線的反向投影。
