Current in resistors is in phase with voltage.

阻器中的压同相。

Since the voltage and current peaks occur at the same time, the two are said to be in phase.

由于压峰值和峰值 同时出现，因此称两者同相。

By seeing how in or out of phase two light waves  are, an observer can infer the relative speed of the waves.

通过观察两个光波的同相异相，观察者可以推断出光波的相对速度。

If undisturbed, the  beams will be in phase, meaning their frequencies will subtract each other, and no light will arrive  at the photodiode.

如果不受干扰，光束将同相，这意味着它们的频率将相互减，没有光到达光二极管。

The gravity waves moving through the inversion  created enough lift that a strong updraft was formed and it moved in phase with the peak of the  gravity wave.

通过反转的重力波产生了足够的升力，形成了强大的上升气，重力波的峰值同相移动。

In that case, vertically polarized light would actually be a superposition of these two diagonal wiggling directions, at least when both are in phase with each other, and they have the same magnitude.

在这种情况下，垂直偏振光实际上是这两个对角摆动方向的叠加，至少当两者彼此同相它们具有相同的幅度时。
