基于空气薄层研究的玻璃遮光效应及折射率测量

A Study of the Effect of Transmittance Light Obstructed of the Glass Based on Thin Air and the Measurement of the Refractive Index of Glass

通过空气薄层发现了玻璃遮光效应产生的亮斑,并对这一现象进行研究,给出相应解释.讨论了玻璃的遮光半径与折射率间的关系,导出遮光半径与玻璃厚度间存在线性函数关系.基于此建立了一种测量玻璃等透明固体物质折射率的新方法.该方法实验操作简单,器材造价低廉,测量精度较高.

This study discovers bright spots produced by the effect of transmittance light obstructed of the glass through thin air and interprets the cause. The paper discusses the relationship between the shading radius and refractive index and deduces the linear functional relationship between shading radius and thickness of glass. Based on the result, a new method of measurement of the refractive index of glass and other transparent solid substances is established. This method features simplicity of experimentation, lower equipment cost, and higher accuracy of measurement.
