本文介绍一个简单测量折射率的物理实验.利用激光束,可清楚地看到介质中光路的折射、部分反射和拿反射现象;并能以较高的精度测定玻璃和液体的折射率.该实验装置包括一个矩形池和一条长边形成顶角为φ的火石玻璃棱镜(参见图1).矩形池和棱镜紧密地联在一起,置于转盘 This article presents a simple physical experiment of measuring the refractive index of a laser beam that clearly shows the refraction, partial reflections, and reflections of the optical path in the medium, as well as the high refractive index of glass and liquid. The device consists of a rectangular cell and a long side of a flint glass prism with a vertex angle of φ (see Figure 1). The rectangular cell and the prism are closely linked together and placed on a turntable
