This extension of the photoelectric effect, in which one photon knocks one electron off the edge of an atom, could make physicists reconsider when light is a wave and when it's a particle.

在这种光电效应的延伸中，一个光子从原子的边缘打出一个电子，这可能要使物理学家们重新考虑光在什么情况下是波，什么情况下是粒子。

So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.

所以我们看到我们用激光笔,还是没有逐出电子，即使我们有这样的强度，它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。

The atoms had an effect called electromagnetically induced transparency (EIT), which enabled the scientists to separate the single-photon precursors from the main wave packet.

这些铷原子可以产生一种称为“电磁感应光透明”(EIT)的效应，可以帮助科学家从主波包中分离出单个光子前驱。

So, we do this here for the photoelectric effect, and in terms of the photoelectric effect, what we know the important point is that the incoming photon has to be equal or greater in energy then the work function of the metal.

所以，我们做这个是为了说明，光电效应，在光电效应方面，我们知道的最重要的事情,就是入射的光子能量必须等于,或者大于金属的功函数。
