例:凸透镜成像实验中,当点燃的蜡烛位于焦点以外时,调节光屏位置,使光屏上呈现一个清晰的烛焰的像。现如果在烛焰和凸透镜之间放上一个凹透镜,此时怎样移动光屏才能再次在光屏上看到清晰的像?解法一:迁移法迁移法就是将已有的旧知识转移到当前需解决的新问题上的一种思维方法,使用迁移法有时会得到事半功倍的效果。例题的情况和近视及近视的矫正相似。试想,人眼球的晶状体和角膜相当于一个
Example: In a lenticular imaging experiment, when the lit candle is out of focus, the screen position is adjusted so that a clear candle flame image appears on the screen. Now if you place a concave lens between the candle flame and the convex lens, how to move the screen at this time to see a clear image again on the screen? Solution A: Migration method Migration method is to transfer existing old knowledge to the current need One way to think of new problems to be solved is to use the migration method to get twice as effective. The case of the case and the correction of myopia and myopia similar. Imagine, the human eye lens and cornea equivalent to one
