Crick was supposed to be completing a thesis on the X-ray diffraction of large molecules.

而克里克则称在完成一篇用X射线衍射大型分子论文。

Sheldon, I was up all night using the new freeelectron laser for my Xray diffraction experiment.

谢尔顿，我整晚都在用新子激光仪做我X光衍射实验。

But the diffraction of centimeter-wave radiation overwhelmed all other shapes and details.

但厘米波辐射衍射淹没了所有其他形状和细节。

And what you will get is this diffraction pattern on the other side.

而你会得到是另一边衍射图案。

Did that mean that the Newtonian explanation of what goes on in diffraction fails?

这是否意味着牛顿对衍射现象解释败了？

But the double-slit experiment isn't the only situation where light creates a diffraction pattern.

但双缝实验并不是光产生衍射图案唯一情况。

Here we're shining a green laser through a diffraction grating that has 500 lines per millimeter.

这里我们使用一束绿色激光穿过每毫米有500条刻线衍射光栅。

And you measured the strength of the diffraction spot with a ruler on a piece of paper.

你用尺子在一张纸上测量了衍射强度。

We also explored the diffraction pattern from a single slit. .

我们还探索了单缝衍射图案。

Finally, we explained the diffraction pattern for a disk.

最后，我们解释了圆盘衍射图案。

And then around the outside of it what we get is diffractions.

然后在它外侧，我们得到是衍射。

And so wave diffraction occurs if we ever have an obstacle or some kind of an opening.

因此，如果遇到障碍物或某种开口，就会发生波衍射。

The astute among you might ask about the higher order beams from a diffraction grating.

你们中敏锐人可能会问关于衍射光栅高阶光线问题。

This pattern is called a diffraction pattern, and it comes from the diffraction and interference of light waves.

这种图案称为衍射图案，它来光波衍射和干涉。

My favorite diffraction pattern, though, is probably that of the Penrose tiling - it's simply gorgeous… not that you see Penrose-tiling-shaped openings very often.

我最喜欢衍射图案，可能是彭罗斯密铺——非常美丽...但彭罗斯密铺形状缺口很少见。

And so by matching the obstacle or the opening to the wavelength, we can get more diffraction.

因此，通过将障碍物或开口大小与波长相匹配，我们可以获得更显着衍射效果。

So that's the packaged lesson about diffraction gratings, but now let's zoom out and remember why we were doing this.

所以这就是关于衍射光栅总结，但现在让我们放大视野， 记得我们为什么要这样做。

At that point, the waves of light that diffracted around the edges of the coin have all traveled the same distance.

那时，围绕硬币边缘衍射光波都传播了相同距离。

And they found that the electrons created a diffraction pattern, just like light did!

他们发现子是被创造出来 衍射图案，就像光一样！

Exactly how this diffraction pattern looks, depends on the spacing of the slits and the light's wavelength.

这种衍射图案外观究竟如何， 取决于狭缝间距和光波长。
