利用光速测定仪测定不同浓度NaCl溶液的折射率

摘要

本实验应用现有的CG-V型光速测定仪，通过对其光路进行改变来测量不同浓度NaCl溶液的折射率，并利用计算机软件（ Excel）对实验的测量数据进行分析处理，探究了NaCl溶液折射率与浓度的定量关系。%The use of existing CG-V type of light detector,by making changes to its optical path to measure the refractive index of different concentrations of NaCl solution,and using computer software( Excel)experimental measurement data analysis and processing,explores the NaCl solution quantitative relationship between the re-fractive index and density.
