Finally, the right project with of approximate calculation difference of light distance is given.
最后给出了两种光程差近似计算的正确方案。
Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.
如果建设新的长途光纤通信网络,Light-line 将是最大的受益公司之一。
This law is known to hold true for galaxies at a distance of at least several billion light years.

So if we just go a tiny distance in here, this is Bud Light and so on.
那么如果我们稍微走点距离,这是百威淡啤酒,以此类推
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。
