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

这很好理解，因为我们看到，原子和分子的能量差为零。

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.

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。

The second strategy was to lower the energy difference between the two conduction-band states so that excited electrons would be more likely to spill over into the photon-emitting state.

第二步策略是减小两个传导带态的能量落差，这样一来受激发电子就更容易溢入光子释放态。

Alexander said the Obama administration's proposed subsidies for solar, wind and agricultural energy development will not make much difference, since those forms of energy provide less than two percent of America's electricity.

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。

The color of the light is mathematically determined by the energy level difference.

In the brain, the signals travelling through the synapses rely on action potential, which is the electrical energy created by the difference in concentrations of charged atoms (ions) on the inside and outside of neuron, which move back and forth through ion channels.

The difference is that energy normally lost through heat in the latter two scenarios is now recovered.
