摘要
本文分析了自准法测定薄凸透镜的焦距实验教学中的一个“奇怪”现象 ,导出把薄凸透镜的第二球面作为反射面时的成像公式 ,利用它可以很好地解释实验教学中的问题 ,并可以测定薄凸透镜的曲率半径和焦距。
A strange phenomenon in the process of determining the focal length of a thin lens by self-collimating method was analyzed.An imaging formula was derived through the way thinking the second sphere of the thin lens as a reflecting surface.The formula could be used for explaining the problems in the experimental teaching and determing the curvature radius and focal length of the thin lens.
