这个能量就是两能级之间的能量差。

That is the difference between these two energy states.

youdao

这很好理解，因为我们看到，原子和分子的能量差为零。

So that should make sense, because we saw no energy difference between the actual atoms and the molecules.

youdao

在这个例子里，能量差较小，我们得到的频率低，这意味这它的波长更长。

So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.

youdao

So this delta energy here is very simply the energy of the initial state minus the energy of the final state.

很简单的，这个能量差等于,初始能量减去末能量。

The formula tells us or absorbed based on the energy difference between the two levels that we're going between, that the electron is transitioning between.

这些公式告诉我们,或发出的光的，频率大小,是基于，电子转移的，两个能级，之间的能量差。

There are some relative, the notion that the energy gap between n equals one and n equals two is greater than that for n equals two to n equals three. That is correctly represented.

还有很多与之相关的内容，比如说这个观点，第一能量级和第二能量级,之间的能量差要大于第二和第三能量级间的,能量差，而这已经被正确地表示出来了。
