摘要
共轭法是一种较为准确和简便的测量薄透镜焦距的方法。这种方法要求物和像的距离 (设为 a)大于 4倍焦距。 a值的取值范围与测量误差有关 ,本文作者阐述了
Conjugate method is an accurate,simple and convenient method to measure the focal distance of thin convex lens.To use this method,the distance between object and image must longer than 4 times of focal length.And the distance has something to do with the error of measurement.The relationship between the distance and the error is expounded in this article.
