一、光电效应的发现在光的照射下物体发射电子的现象,叫做光电效应.有趣的是,如果说光电效应是光的粒子性的实验证据,发现这一效应却是赫兹在1887年研究电磁波的波动性质时的意外所得.他用两套放电电极做实验,一套产生振荡,发出电磁波;另一套充当接收器.电极之间存在火花放电的缝隙.他发现当紫外光照在负电极上时,放电就比较容易发生.赫兹的论文“紫外线对放电的影响”发表后,引起了许多物理学家的注意.1888年,德国物理学家霍尔瓦希和俄国的斯托列夫(Ctojietob),他们各自独立地 First, the discovery of photoelectric effect In the light of the object under the electron emission phenomenon, called the photoelectric effect.It is interesting that if the photoelectric effect is the experimental evidence of the particle of light and found that this effect was Hertz in 1887, the study of electromagnetic waves Of the fluctuating nature of the accidental income he used two sets of discharge electrodes to do the experiment, a set of oscillations, the issue of electromagnetic waves; the other as a receiver. There is spark gap between the electrodes. He found that when the UV light shines on the negative electrode The discharge was relatively easy to occur.Hertz’s paper “the impact of ultraviolet radiation on the discharge,” published aroused the attention of many physicists.In 1888, the German physicist Holvash and Russia’s Stolov (Ctojietob ), They are each independently
