| Abstract: | 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. |
