一、圆柱形容器底部为什么呈现3字形的光迹?当阳光或较远的灯光射到圆桩形的器皿内侧,侧器皿底部常呈现3字形的反光。当平行的光线照射到圆形的凹反射面时,每一条光线都遵守反射定律,入射角等于反射角.越多反射光线经过的地方,也就照得越光亮,故3字形的反射光就是由无数的反射 1. Why does the bottom of a cylindrical container show 3-shaped light traces? When the sun or distant light strikes the inside of a round-shaped container, the bottom of the side container often exhibits a 3-line reflection. When parallel rays hit a circular concave reflective surface, each light follows the reflection law and the angle of incidence is equal to the angle of reflection. The more reflections the light passes through, the brighter it shines, so the reflection in the shape of a three is From countless reflections
