近年来,以凸透镜知识为命题背景的实验题越来越多,这类实验题较贴近学生的生活,将相关物理基础知识和操作技能的考核隐藏在题目中。我们需要通过对题目中的素材、图像等相关信息进行分析,弄清题目中隐含的解题信息以及思路,然后进行推理、探究和发现,直至最后解决此类题目。目前透镜类实验题在考查中常见的有三种类型,下面精选部分题目加以分析归纳。一、以凸透镜基础知识的探究为命题背景的实验题。凸透镜作为生活中应用很广泛的光学器件,它
In recent years, with convex lens knowledge as the proposition background more and more experimental questions, these experimental questions are closer to the student’s life, the relevant basic knowledge of physics and operational skills assessment hidden in the title. We need to analyze the subject matter, images and other related information in the subject, to find out the problem information and ideas implied in the title, and then to reasoning, exploring and discovering, until the final solution to such problems. At present, there are three types of lens test questions that are commonly found in exams. The following selected topics are analyzed and summarized. First, to explore the basic knowledge of convex lens as the proposition background experimental questions. Convex lens as life is widely used in optical devices, it
