摘要
对测量凸透镜焦距的传统实验方法进行改进,采用激光为光源进行测量的一种新型简易方法,该方法操作简单,可直接读取焦距测量值。实验结果表明,测量结果与传统方法相比更准确。
This essay is to improve the traditional method for measuring. Convex lens focal length,and use a new measurement method of taking a laser light as source. The method is simple to read directly measured.Value of the convex lens focal length.The experimental show that this. Measured method produces more accurate results than the traditional did.
