The augmented equations, today known as the Maxwell equations, described a unified theory of electricity and magnetism. The new equations showed that light is a moving, self-renewing disturbance in electrical and magnetic fields, and they predicted that new kinds of disturbances are possible.
经过完善的方程组，即麦克斯韦电磁方程组描述了关于电和磁的统一理论。该方程组表明，光是电磁场中一种运动的、自我更新的波，并且预言存在新的电磁波类型的可能性。
