No, OK and that's correct, because each photon of light actually has more energy than is needed to eject an electron.
没有,好,对了,因为每一个光子实际上,都有更多的能量去逐出一个电子。
So in this case, we don't have enough energy to eject an electron, so, an electron is not ejected.
所以在这种情况下,我们没有足够的能量,去逐出一个电子,这样没有电子被逐出。
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。
