So what we're saying here is the incident energy, so the energy coming in, is just equal to the minimum energy that's required to eject an electron.

这里我们来讨论一下，入射能量正好等于,发射出一个电子所需要的最低能量的情况。

We're only using up a little bit to eject the electron, then we'll have a lot left over.

如果我们只需要用很少一部分来发射出电子，那么我们可以得到很多的剩余能量。

So we can use an equation to relate the incident energy and the kinetic energy to the ionization energy, or the energy that's required to eject an electron.

因此我们可以用一个公式将入射能量,与动能和电离能，就是发射出一个电子所需要的能量关联起来。

It makes sense that it's going to come out of the highest occupied atomic orbital, because that's going to be the lowest amount of energy that's required to actually eject an electron.

从最高占据轨道上,去掉一个电子是合理的，因为这样是发射一个电子,所损失的最低能量。

we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.

当我们从高到低时，我们说的,是发射,电子有多余的能量给出，这个能量等于，发出,光子的能量，当然我们可以通过方程,从能量知道，光子的频率，和波长。
