One of the major contributions of Maxwellian theory was that it set up an essential relation between the electromagnetic field and light in vacuum, and defined the speed of electromagnetic wave as the constant speed of light c , which implies a hypothesis that the rest mass of the photon should be zero exactly.

麦克斯韦电磁理论的一个重要贡献在于它将真空中的电磁场与光联系起来，并将电磁场的传播速度定义为真空的属性，即恒定的光速 c ，因而建立了电磁波与光之间的本质联系。
