So, if something cycles through five wavelengths in a single second, we would just say that the frequency of that wave is five per second.
如果一个东西在一秒,内经历了五个波长,我们就说这个波的,频率是每秒5次。
The one thing you want to keep in mind though is that Hertz does not actually mean inverse seconds, it means cycles per second. So, if you're talking about a car going so many meters per second, you can't say it's going meter Hertz, you have to say meters per second.
写成5每秒,或5赫兹,你们要记住的是赫兹,并不等于秒的倒数,它是每秒的循环数,如果你们说,一辆车一秒可以走多少米,你不能说它走了米赫兹。
