摘　　要：根据牛顿环等厚干涉的基本原理,在传统测量平凸透镜曲率半径的基础上,对牛顿环实验进行实验内容与实验方法方面的拓展.实验内容拓展包括测量介质折射率、单色光波长以及测量玻璃弹性模量,实验方法拓展包括用激光法和分光计法分别测量平凸透镜曲率半径.这些拓展性实验丰富了牛顿环等厚干涉的实验内容,促进了物理实验方法和实验技术的融会贯通,能够激发学生探索创新的热情,提高综合应用物理知识解决实际问题的能力.According to the basic principle of equal-thickness interference of Newton′s rings,on the basis of the traditional measurement of the curvature radius of plano-convex lenses,we designed an extension of the experimental contents and experimental methods for the Newton′s ring experiment.The expansion of the experimental contents includes the measurement of the refractive index of the medium,the wavelength of monochromatic light,and the measurement of the elastic modulus of glass.The expansion of the experimental methods includes measuring the radius of curvature of the plano-convex lens by the laser method and the spectrometer method,respectively.These extensive experiments enrich the experimental contents of equal-thickness interference of Newton ring,promote the integration of physical experimental methods and experimental techniques,stimulate students′enthusiasm for exploration and innovation,and improve their ability of comprehensively applying physical knowledge to solve practical problems.
