|
Abstract:
本文对测量凸透镜焦距的传统实验方法进行改进，采用激光作为光源进行测量的一种新型方法。此方法基于凸透镜汇聚光线，激光沿直线传播，平面镜成像等原理，可直接读取焦距测量值，综合性较强，结果较传统方法更准确。
In this paper, the traditional experimental method of measuring focal length of convex lens is improved, and a new method of measuring the focal length of convex lens using laser as light source is introduced. This method is based on the principle of convex lens converging light, laser propagating along a straight line, plane mirror imaging and so on. It can directly read the measurement value of focal length, which is more comprehensive and more accurate than that of traditional method.
