摘要
用通常的实验装置演示光电效应现象 ,由于所产生的光电流很弱 ,因而现象不明显 ,不易观察 ,我们在原有的实验装置中增加了一个放大电路 ,将光电流加以放大 ,从而改进了实验效果 ,本文介绍用改进后的装置 ,演示实验的情况 .
Physical phenomenon is not very clear if we demonstrate photo emission by usual experimental apparatus. So that it is not easy to observe it owing to the feeble photo current. We have modified the apparatus in which increase an amplifying circuit in order to enlarge current. This paper introduces the demonstration by new apparatus.
