摘要
关于凹透镜焦距的测量方法已经有很多研究,本文提出了应用实物成虚像、虚物成虚像方法来测量凹透镜的焦距,并与虚物成实像方法进行比较和分析.本文的实验研究拓展了凹透镜焦距测量的实验思路,同时更加深入理解了透镜的成像规律.
There have been a lot of works on the measurement of the focal length of concave lens. This paper proposes the method for measuring the focal length of concave lens by appli- cations of the real objects into the virtual image and the virtual objects into the virtual image, which are compared and analyzed with the virtual objects into the real image method. Experi- mental research of this paper expands the experimental idea of measuring the focal length of concave lens. At the same time, the imaging rules of lens are more deeply understood.
