To deflect means to make something change direction.

折射就是使某物改变路径。

The mist is refracted by daylight to produce rainbows.

水雾被日光折射，形成了彩虹。

This refraction has a couple of interesting results.

这种折射可以导致几个有趣的结果。

And if it's bending towards this normal line...

如果它的折射光线靠近这条垂线。

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

今天我们要讲的是光线的折射。

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

慢光波改变了其方向，这个过程被称为折射。

So the moonlight we see is reflected white light from the Sun.

所以我们看到的月光是来自太阳光的折射。

Those telescopes that do not employ reflection use refraction.

那些不利用反射的望远镜利用的是折射。

The minds behind them were not savage, just “untamed”.

神话背后折射出的不是一群野蛮人的思维，只是“未驯服的”思维。

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

我不是科家，所以我要猜 C. 折射。

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

当光线照射到这些层时，它会通过一个叫做折射的过程弯曲。

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

是 A. 散射，B.反射，还是 C. 折射？

Rainbows are made when water droplets in the air bend sunlight much like a prism.

像棱镜那样，当空气中的水滴将太阳光折射出来，就形成了彩虹。

And if you look in the orchestra today, you just don't see society reflected.

可是如果你看看今天的管弦乐队，你可能发现不了它折射的社会。

(Or, rather, they divided a computer representation of each mirror.)

（或者说，是对显示每个镜体吸热量和折射热量效果的电脑程序做了细分）。

But what if the object in question did not absorb, refract or reflect electromagnetic radiation at all?

但是，如果现在讨论的物体根本不吸收、折射或反射电磁辐射呢?

This bending and reflecting splits the light and the colours hidden inside the white sunlight are revealed.

折射和反射的过程起到了分光的作用，于是七色阳光呈现在我们眼前。

This substance has a high refractive index, meaning the speed of light passing through it is greatly reduced.

这种物质的折射率很高，意味着光穿过它的速度会大幅降低。

Now, magicians have figured out how to utilize full-sized mirrors to bend light in order to create disappearing illusions.

现在，魔术师已知道如何利用全身镜折射光线制造出隐形的假象。

The layers only appear white because the air spaces in each hair scatter all visible wavelengths of light.

我们之所以看到的是白色，是因为北极熊毛发中空部分对光线的折射造成的。
