摘要：光在介质中的传播遵循费马原理.在均匀介质中光沿直线传播,非均匀介质中,光的传播轨迹比较复杂.本文以蔗糖溶液为研究对象,设计了光在非均匀介质中传播实验,建立了相关模型,理论分析了溶液折射率随深度(浓度)变化的关系.进行了数据拟合,得出溶液折射率随液体深度变化的表达式.
The propagation of light in the medium follows Fermat s principle.In homogeneous medium,light propagates along a straight line,and in inhomogeneous medium,the propagation trajectory of light is more complex.In this paper,taking sucrose solution as the research object,the experiment of light propagation in inhomogeneous medium is designed,the related model is established,and the relationship between the refractive index of the solution and the concentration is analyzed theoretically.The gradient expression of refractive index of solution is obtained by fitting the data.
