凸透镜成像在日常生活中的应用有很多,如照相机、投影仪(幻灯机)、放大镜等.有些同学在学习这部分内容时,由于对凸透镜成像规律记忆不准确、理解不透彻、实验操作不规范,往往会导致错误.易错点Ⅰ:对凸透镜成像规律的记忆透镜分为凸透镜和凹透镜.凹透镜成的像是正立、缩小的虚像,凸透镜的成像规律及其应用如表1.有些同学会因为对凸透镜成像规律的记忆混乱而出错.
There are many applications of convex lens imaging in daily life, such as camera, projector (slide projector), magnifying glass, etc. Some students study this part of the content, because of the imaging lens imaging is not accurate, the understanding is not thorough, the experimental operation is not standardized, Often lead to errors. Easy to make mistakes Ⅰ: The law of the imaging lens imaging convex lens is divided into convex and concave lens. Concave lens into the image is upright, reduced virtual image, convex lens imaging and its application in Table 1. Some students because of Convex lens imaging disorder memory error.
