凸透镜成像是初中光学中的重要内容,又是各地中考的必考内容.熟记并掌握凸透镜成像规律是解答问题的关键.表1是从探究凸透镜成像的实验中收集到的现象.相信同学们都能熟记表格中的内容.然而,以往在学习中同学们只是对表格做诸如熟记之类的简单处理就结束了,没有对现象深入的分析和归纳.对凸透镜的成像规律的掌握只停留在表面,而没有抓住关键和本质.所以就感到凸透镜成像的规律零碎难记,熟记的“规律”对有些题“不管用”等.
Convex lens imaging is an important part of junior high school optics, but also the necessary examinations in all areas.Make reference to and master the law of convex lens imaging is the key to answer the questions.Table 1 is from the exploration of the imaging of convex lens imaging phenomenon .I believe the students But can memorize the contents of the form.However, in the past, students in the past just to do the form, such as memorize the simple process is over, there is no in-depth analysis and induction of the phenomenon of the imaging lens Stay on the surface, but did not grasp the key and essence.So we feel the regular lens imaging lens system difficult to remember, memorize “rule ” for some questions “do not care ” and so on.
