光线经透镜折射以后不但能改变光线的传播方向,而且能够成像。透镜的成像规律,可以通过实验的方法来探究,还可以借助透镜的三条特殊光线作图寻找。利用透镜三条特殊光线解决有关成像问题,具有简捷、灵活的优势。一、确定像的位置
After the light is refracted by the lens, it can not only change the direction of light, but also can image. The imaging law of the lens can be explored through experimental methods, and three special ray tracings of the lens can also be found. Using the three special rays of the lens to solve the imaging problem, it has the advantages of simplicity and flexibility. First, determine the location of the image
