运动电荷可以产生波动。其波动机理为：运动电荷e运动时，必然受到其毗邻e地阻碍，表现为运动电荷带动其毗邻1向上运动，即毗邻随同运动电荷e一起向上运动；当毗邻1向上运动时，必然受到其自身毗邻1地阻碍，表现为毗邻1带动其自身毗邻向上运动，即毗邻2随同毗邻1一起向上运动
因为这些各异的电磁辐射在“简单”层面上，即本质上是如此相似，所以如今把它们视为一个光谱中的组成部分。
Because these different forms of electromagnetic radiation - on this "simplistic" level - are fundamentally so similar, they are today commonly viewed as composing a single spectrum.
