摘要
光在水珠表面的反射、水珠内的反射、折射起主要作用。根据光的电磁理论,水珠表面直接反射、经二次折射进入观察者眼中的光能占入射能量的绝大部分,所以,水珠晶莹透明,在阳光照耀下格外明亮。
It is a common phenomenon that dewdrops are clear and shiny, especially in the sunshine. The reason for this is that it's the combined effect of the reflex of the light on the surface of the drops, the reflex and the refraction in the drops. According to the magnet theory of light, the surface of drops reflects directly. From the second refraction, the light energy which entered the eyes of the observer takes a large proportion of the incident light energy.
