光波与无线电波的差异与统一光波与无线电波都是电磁波,由于二者的产生方法有重大差别,因而过去对它们有截然不同的看法。现代的无线电波通常由电子管振荡器产生,这实质上是大量自由电子在电路(或波导)中形成的振荡运动,其频率由电路的谐振特性决定,这种谐振最后显示在发射天线上,电磁波由此发送。电磁波的一种频率表示一种“颜色”,频率越纯,单色程度越高。 Differences between Lightwave and Radio Waves and Uniform Lightwaves and Radiowaves are all electromagnetic waves. In the past they all had very different opinions due to the significant differences between the two methods. Modern radio waves are usually generated by a tube oscillator, which is essentially the oscillating motion of a large number of free electrons formed in the circuit (or waveguide), the frequency of which is determined by the resonant characteristics of the circuit, which is finally displayed on the transmitting antenna. The electromagnetic waves Thus sent. A frequency of electromagnetic waves represents a “color”, the purer the frequency, the higher the degree of monochromaticity.
