"With reform, we will make our financial system more transparent by bringing the kinds of complex backroom deals that helped trigger this crisis into the light of day."

We know that UV light gets absorbed by glass, so it shouldn't be able to go through the glass.

我们知道紫外光会被玻璃吸收，所以它无法通过玻璃。

And the relationship that he put forth is that the momentum is equal to Planck's constant times nu divided by the speed of light, or it's often more useful for us to think about it in terms of wavelength.

爱因斯坦提出的关系式是,动量等于普朗克常数,乘以υ除以光速，或者用波长来表示,通常更容易让我们想明白。

Though Iran was to respond by Friday, the International Atomic Energy Agency said Iran told it that while it was considering the plan in a favorable light it needed until the middle of next week to make a decision.

On day four, The heavenly bodies that give off light by day or night are created.

在第四天，那些在白天或者晚上发光的天体被创造了。

They are supposed to take that light out, but maybe by the end of the semester a miracle will occur. So why don't you look over here.

他们应该把灯关掉，但是可能直到期末这个奇迹,才会发生，所以，你们看这边吧。

It's now exactly that power from which Milton has been excluded by virtue of his blindness -- light: "Hail holy Light, offspring of Heav'n first-born, / Or of th' Eternal Coeternal beam May I express thee unblam'd?"

而是弥尔顿已经被失明剥夺的一种力量,圣光，你是上帝最初的产物，永恒的光束,我是否可以向你表达我无限的敬意“

So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.

所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。

So, most people could recognize that light wave a has the shorter wavelength. We can see that just by looking at the graph itself -- we can see certainly, this is shorter from maxima to maxima.

0秒钟，好的，不错大部分,同学都可以判断出来这个光波的,波长更短，我们仅通过,看图就能看出来-可以。

So, since the speed of light equals lambda nu, we can say that momentum is equal to h divided by lambda.

所以，既然光速等于λ乘以υ,我们可以得到动量等于h除以λ

Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.

好了，我们已经定义了，这些术语，我们知道了，频率和波长，现在可以来考虑,波的速度了，特别是光波的速度，速度等于它走过的距离,除以所用的时间，因为我们。
