牛顿环干涉实验问题探究

针对牛顿环干涉实验中数环数、牛顿环装置接触中心圆面大小以及汞光波长测量结果等几个问题,用同一个牛顿环装置进行了多次实验测量并处理实验数据,得到的结果表明,适当地增加数环环数和牛顿环装置接触中心圆面要有适当大小以保持平凸透镜稳定地立于平板玻璃之上,可有效提高凸面半径测量结果的准确度,并可有效减小随机偏差。此外,根据汞光光谱各谱线的相对强度,能够解释汞光波长的单一测量结果。

Study on Newton Ring Interference Experiment

Aiming at some problems with a Newton ring device carried out several experiments measur- ing and processing of experimental data, the results obtained show that, properly increasing number of ring number and Newton ring device contact appropriate size center area in order to maintain stability in the plano convex lens plate glass, can effectively improve the accuracy of measurement results of convex radius, and effectively reduce the random deviation. In addition, according to the relative strength of the mercury light spectrum line,it can explain the single measurements of mercury wavelength.
