在高中《物理》(甲种本)第三册《全反射》一节中,提到自然界的全反射现象时指出“露水珠或喷泉的水珠,在阳光照耀下,格外明亮,也是因为射进水珠的光在水珠内发生全反射。”教材中的这种看法值得商榷。众所周知,人们所以能看到物体甚至感到格外明亮,是因为有较强的光线从物体内部或表面射到人的眼 In the section “Total Reflexes” in the third volume of “Physics” (A type of book) in high school, when referring to the phenomenon of total reflection in nature, it was pointed out that “beads of dew drops or fountains are particularly bright in the sun, but also because The light that hits the waterdrops is totally reflected in the waterdrops." This view in the textbook is debatable. As we all know, people can see that an object feels even brighter because it has stronger light rays that reach the person’s eyes from the inside or the surface of the object.
