Those telescopes that do not employ reflection use refraction.

那利用反射的望远镜利用的是折射。

Is it a) dispersion, b) reflection, or c) refraction?

是 A. 散射，B.反射，还是 C. 折射？

Hmmm, well, I'm not a scientist, so I'll have a guess as c) refraction.

我是学家，所以我要猜 C. 折射。

Slowing a wave changes its direction, a process called refraction.

放慢光波改变了其方向，这个程被称为折射。

This refraction has a couple of interesting results.

这种折射可以导致几个有趣的结果。

And when light hits these layers, it bends through a process called refraction.

当光线照射到这层时，它会通一个叫做折射的程弯曲。

The problem here is that the water actually changes the refraction of light.

问题在于，水实际上改变了光的折射。

Now we're going to talk about refraction of light.

今天我们要讲的是光线的折射。

So instead, many researchers are trying to reroute wavelengths around an object using refraction.

因此，许多研究员正尝试利用折射原理，使光线绕物体，从而改变其传播路径。

Refraction describes how light changes direction when it passes between materials of differing density.

折射描述了光在通密度的材料时如何改变方向。

But to see if this was true for refraction would be difficult.

但是要确定折射是否如此会很困难。

When both of these tones play, those compression and refraction waves interfere with each other.

当这两种音调时播放时，那压缩波和折射波会相互干扰。

That is a special crystal that has two different indices of refraction.

这是一种特殊晶体，具有两种的折射率。

It is turning upside down due to the refraction of the light coming through.

由于光线的折射，它正在颠倒来。

I actually think it's a refraction of reality.

实际上，我认为它是现实的折射。

And in fact, many ships in the area of Titanic's crash talked about abnormal refraction.

事实上，泰坦尼克号撞船地点附近的许多船只都提到异常折射现象。

How does that change the law of refraction?

这怎么能改变折射定律呢？

And this notion, you might have heard people call it refraction.

这个概念，你可能听们称之为折射。

And we talk about that in another video, and we call that refraction.

我们在另一个视频中讨论了这一点，我们称之为折射。

The discovery of negative refraction kicked off the modern wave of invisibility research.

负折射现象的发现，掀起了现代隐身术研究的新浪潮。
