Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.
好了,我们已经定义了,这些术语,我们知道了,频率和波长,现在可以来考虑,波的速度了,特别是光波的速度,速度等于它走过的距离,除以所用的时间,因为我们。
We have a habit in this society to think that individual rights, when they drafted the Bill of Rights, was just laid down for us and it's just traveled through time and here they are.

The period, that's right. So, it's going to take one period to move that long. And another way 1 we can say period is just 1 over nu or 1 over the frequency So, now we know both the distance traveled and the time the elapsed.
还是?周期,对的,它需要一个周期的时间,另一种说法是周期是,除以nu,也就是1除以频率,现在我们同时知道了。
So, we can just plug it in. Speed is equal to the distance traveled, which is lambda over the time elapsed, which is 1 over nu. so, we can re-write that as speed is equal to lambda nu times nu, and it turns out typically this is reported in meters per second or nanometers per second.
经过的距离和所花的时间,我们把它们带进来,速度等于经过的距离,也即是lambda除以,所花的时间,通常它的单位,是米每秒或者纳米每秒。
