基于三种色散公式的三棱镜色散实验研究

Study on the Triple Prism Dispersion Experiment Based on the Three Kinds of Dispersion Formula

利用分光计得到了汞灯透过三棱镜后五种不同谱线的最小偏向角,计算出了它们的折射率,基于Cauchy,Hartmann,Conrady三种色散公式,拟合得到了三种不同色散公式的的色散系数和色散曲线。

Using the spectrometer to measure triple prism＇ s minimum deviation angle of five different wave- length of light from mercury lamp light and calculating their refractive index.Then using Cauchy, Hartmann, Conrady dispersion formula to fit the experimental curves, get the dispersion curves and dispersion coefficients.
