折射率的测定玻璃或留西特(一种有机玻璃——译者注)的折射率的测定是一年级第二学期学生要做的一个传统实验。在一个装备较好的物理实验室中,一个很适用的最精密的测定方法是利用一个精密的分光计来测量一个等边棱镜的最小偏向角。不幸的是,在许多系的设备预算中,都排除了在新生实验室使用 Refractive Index Determination The refractive index of glass or Rexroth is a traditional experiment to be performed by the first semester of the first semester. In a well-equipped physical laboratory, one of the most sophisticated methods of measurement is the use of a precision spectrometer to measure the minimum deflection angle of an equilateral prism. Unfortunately, many departmental equipment budgets exclude use in freshmen laboratories
