由于大多数相机闪光灯在发出可见光同时就会发射出红外线，这一替换使得原型机能够发送并记录红外线。

Since most camera flashes emit IR along with their burst of visible light, the one substitution allowed the prototype to transmit and record infrared light.

So we can actually pop an electron or eject an electron from any single orbital that is occupied within the atom.

任何一个被占据轨道,打出一个电子,或者说发射出一个电子。

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。

The electron's going to come out of that highest occupied atomic orbital, that one that's the highest in energy, because that's going to be the at least amount of energy it needs to eject something.

这个电子应该是从,最高的被占据轨道上出来的，它的能级是最高的，因为这样的话发射出它,只需要消耗最少的能量。
