凸透镜成像是中学物理的一个教学重点。本文试根据学生机械套用公式、不注意符号规则等问题,论述抓住实验搞好凸透镜成像规律的总复习。1 再现实验 1.观察实验装置,重温实验器材。 2.做成像实验,重忆成像实验步骤。
Convex lens imaging is a teaching focus of middle school physics. This article tries to discuss the general review of the imaging law of the convex lens by grasping the experiment according to the problems of the students’ mechanical application formulas and the rules of not paying attention to the symbols. 1 Reproduce the experiment 1. Observe the experimental device and relive the experimental device. 2. Do an imaging experiment and recall the imaging experiment steps.
