MATLAB Visualization of the Exit Angle, the Deviation Angle and the Refractive Index of a Triangular Prism
【摘要】 利用分光计测量三棱镜折射率是典型的大学物理实验之一。利用出射角和偏向角的公式,分析了临界角的分布规律,推导了最小偏向角的公式。通过旋转三棱镜说明了折射率的测量方法.应用MATLAB绘制了曲线(族)和曲面.附录中的MATLAB程序比较完整,可以直观演示并解决上述问题,可供读者参考。
【Abstract】 Measuring the refraction index of a triangular prism by spectrometer is one of the typical college physics experiments.Based on the formulas of exit angle and deviation angle, we analyzed the distribution law of critical angleand deduced the formula of minimum deviation angle, and illustrated the measurement method of refractive index by rotating a triangular prism.Then, the curves(curve family) and curved surface were plotted by MATLAB.The MATLAB program in the appendix is relatively complete, which can intuitively demonstrate and solve this above problems for readers’ reference.
【Key words】 triangular prism; inclination angle; exit angle; deviation angle; refractive index; MATLAB program;
