19世纪60年代英国物理学家麦克斯韦建立了电磁场理论,其包含的深刻和创新的思想一时还难以为人们所理解,需要有力的实验证据.1879年德国柏林科学院悬奖征求对麦克斯韦理论进行实验验证,促使年轻的赫兹萌发了进行电磁波实验的热情.赫兹实验中所用的装置如图1所示,振子为直线型开放振荡器,铜棒上各接一个小铜球,两球中间留有空隙,两棒分别接到感应线圈的两端.当通电时两球之间产生放电,形成电磁振荡.为了探测由振子发射出来的电磁波,赫兹采用圆形铜环作为接受装置——谐振器.将谐振器放在距直线振荡器一定的距离以外,适当地选择方位,
In the 1860s British physicist Maxwell established the theory of electromagnetic field, which contained profound and innovative ideas for a short period of time can not be understood by people, and requires strong experimental evidence. Berlin, Germany, 1879 Suspension of the solicitation of Maxwell theory for experimental verification , Prompting the young Hertz germination of the enthusiasm for electromagnetic experiments.Hertz experimental device used in Figure 1, the oscillator is a linear open-type oscillator, each connected to a small copper ball on the copper, leaving the gap between the two balls, Two rods are respectively connected to the two ends of the induction coil. When the power is applied, a discharge is generated between the two balls to form an electromagnetic oscillation. In order to detect the electromagnetic wave emitted by the vibrator, a circular copper ring is used as a receiving device and resonator. Place the device at a distance from the linear oscillator, select the correct orientation,
