摘要
通过自主设计的透镜焦距测量实验装置以最简单、直观的方式阐述了光的折射原理。该实验设计以光学基本原理为切入,循序渐进地引导学生从科学角度全面系统地认识透镜,明确透镜介质与其所处环境介质折射率的内在联系,抓住问题本质,设计出一种透镜焦距连续可调的新方法。
This paper clarifies the principle of light refraction in the simplest and most intuitive way through self-designed lens focal length measurement experiment instruments.Based on the principle of light refraction,the experiment guides students to understand the essence of the lens and clarify the relationship between the refractive index of the lens and the refractive index of the environmental medium.The experiment enables students to design a new method for continuousad just ment of focal length of lens.
