凸透镜成像是光学中的一个主要内容,学生虽能记住透镜的成像规律及成像公式,但在教学中发现,许多学生不能充分利用其成像的特点对动态问题(因物体或透镜移动而引起的讨论)进行正确分析.下面笔者就这方面内容作一归纳.一、透镜成像特点1.成像图
Convex lens imaging is a major part of optics. Although students can remember the imaging laws and imaging formulas of lenses, many students find that they cannot fully use the characteristics of their imaging for dynamic problems (due to the movement of objects or lenses). Discuss) Perform the correct analysis. The author hereby summarizes this aspect. First, the lens imaging features 1. Imaging diagram
