Intensity, if we increase the intensity, we're not increasing the energy in each photon, we're just increasing the number of photons that we're shooting out of our laser, whatever our light source is.

强度，如果我们增加强度，我们增加的不是,每个光子的能量，我们增加的仅仅是,从我们激光源射出的光子数，无论我们的光源是什么。

If we think that our knowledge is positive, we say "red" in a red light means stop.

如果我们主动认知，红灯的意思是停。

I wonder if there's some UV light out of this new lighting set up in our classroom here.

好的，我想知道这里,我们教室里的这套新的照明装置,是否有一些紫外光出来。

It makes me feel even worse that everybody else is stuck dying-- or perhaps we should say dying too soon in light of our discussion about immortality.

所有人都为死而苦恼让我感到更糟糕-,或者我们应该说,按照我们对永生的讨论，是死得太早。

Murder is murder in every way and our society looks at murder down on the same light and I don't think it's any different in any case.

不论怎么解释，谋杀依然是谋杀,社会对待谋杀是一视同仁的,不论如何，都没有任何不同。

So if we think about the work function for zinc, and the work function for zinc is 6.9 times 10 to the -19 joules, do we expect that when we shine our UV light on the zinc, we'll be able to eject electrons?

如果我们考虑锌的功函数,它是6，9乘以10的-19次方焦耳，我们是否可以预测当,用紫外灯照射锌时，我们可以射出电子呢？

All right, but still it's a red light, right, and our hypothesis is that the red light has positive value in the sense that it means a certain thing. It means, we say, "stop."

它是一个红灯，我们假设红灯主动自带含义,它代表着，停“

So you know that x-rays are higher frequency than UV light, for example, that means it's also higher energy than UV light, and if you think back to our photoelectric effect experiments, do you remember what type of light we were usually using for those? Does anyone remember?

你们知道，X，射线的频率比紫外光高，这意味着，它的能量也比紫外光要高，那么，请大家回想一下我们的光电效应实验，大家还记得当时我们用的是什么光源吗？,有人记得吗？
