摘要
凸透镜成像的规律,大部分学生往往难以记住。在分析解决实际问题时更会感到十分茫然,用作图法研究凸透镜成像规律,就会使学生做到画而了知,经久不忘。
The rule for convex lens imaging is difficult for most of the students to remember.Students would feel very ignorant when solving the practical problems.When applying graphing method to study convex lens imaging rule,students would be able to know the rule by drawing the graphs,and they would not forget this rule for a long time.
