摘要
介绍了利用分光计测量透明液体折射率的一种实验方法 ,实验中使用了两个等边三棱镜 ,将液体夹在两棱镜之间形成厚度均匀的液膜 ,利用全反射原理对液膜进行测量 .结果表明 ,这种实验方法操作简便 ,重复性好 ,准确度高 .
The experiment method of measuring refractive index of transparent liquid with spectrometer is improved.In the experiment two equilateral triangular prisms are used to sandwich liquid between them to form a regular liquid film and the film is measured by using total reflection principle.As a result,this method is easy to operate with steady repetition and high degree of accuracy.
