And all we mean by constructive interference is that literally those two waves add together, such as the maxima are now twice as high, and the minima are now twice as low.

相干相长，相干相长也就是,说两个波加在一起，所以最大值变成2倍那么高，最低值变成2倍那么低。

So, most people could recognize that light wave a has the shorter wavelength. We can see that just by looking at the graph itself -- we can see certainly, this is shorter from maxima to maxima.

0秒钟，好的，不错大部分,同学都可以判断出来这个光波的,波长更短，我们仅通过,看图就能看出来-可以。

And, if you laid this out in a table, as Mendeleev did with his cards, you would find that the local maxima all occur roughly in the same horizontal position from the end points of the rows.

如果你们这些放到一张表格上去，像是门捷列夫用纸牌做的那样，你会发现局部的最高点,会出现在同一个水平高度,从这些行的最后一点。
