思路启发(超过40个字)无论是凸透镜还是凹透镜,通过光心的光线不改变方向.平行于凸透镜主光轴的光线经凸透镜折射后经过凸透镜的焦点.(平行于凹透镜主光轴的光线经凹透镜折射后经过入射线同侧凹透镜的焦点.图中没画出这条光线)_______________________________________________________________
解答过程:见上图._________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
答案:无论是凸透镜还是凹透镜,通过光心的光线不改变方向.平行于凸透镜主光轴的光线经凸透镜折射后经过凸透镜的焦点.平行于凹透镜主光轴的光线经凹透镜折射后经过入射线同侧凹透镜的焦点.
