" That one, then. The roll unwinds. The selenium cells transform the light impulses into sound waves, and … "

“那一个，然后，录音带展开，硒质光电管把光波转化为声波，于是… … 。”

The wave carries information from the object that your brain uses to create an image.

光波携带着物体信息，让你大脑能建构影像。

The energy needed for plants to grow is contained in photons – or light particles, travelling at different wavelengths – distances between light waves which make things look different colours.

植物生长所能量包含在光子或光粒子中，它们以不同波长传播——波长是光波之间距离，它使事物呈现出不同颜色。

Instead of traveling across the radiative zone and hitting your eye, the light waves slam into electrons and other particles in the plasma.

光波不会穿越辐射区然后击中你眼睛，而会撞上电子和等离子体中其他颗粒。

So how do we transform light waves into meaningful information?

那么我们如何将光波转换成有意义信息？好吧，让我们先从？

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

放慢光波改变了其向，这个过被称为折射。

When waves of light enter the feather, they bounce off of those layers.

当光波进入羽毛时，它们会从这些层反弹回来。

This is a kind of light wave that mice and humans cannot normally see.

老鼠和人类通常看不见这种光波。

It splits waves of light along two parallel arms and eventually rejoins them.

它把光波分成两条平行臂，并最终重新连接起来。

Planck's equation stated that light waves carry energy in small packets called 'quanta'.

普朗克出，光波以被称为“量子”小包携带能量。

They used it to beam the prisoners instantaneously up to Fort Rozz.

它光波能把犯人们瞬间传送到罗兹堡。

And when you detune the radio a bit you can just hear static, but about 1% of that static is music to the ears of a physicist, because that is stretched light from the Big Bang.

当我离开某个频率时，会听到噪音，但这噪音中有 1% 部分是物理学家最爱，因为这就是大爆炸之后那一缕光波遗迹。

Into the clearing where the moonlight streamed, they poured in a silvery flood; and in the centre of the clearing stood Buck, motionless as a statue, waiting their coming.

空地上洒满了月光, 他们像一股银色光波一拥而入, 巴克站在空地当中, 静等着他们到来, 如一尊雕像一般。

This is a device that can precisely measure the wavelength of light, and can for example distinguish light emitted by a hydrogen atom from light emitted by helium.

这是一种可以精确测量光波长设备，例如，它可以区分出氢原子发出光和氦发出光。

This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. This radiation , in its turn is absorbed and reemitted.

这种伽玛射线被太阳内原子所吸收，然后重新释放为波长稍长一些光波。这新射线再次被吸收，而后释放。

Townes and Arthur Schawlow, then at Bell Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves.

在贝尔电话实验室，就如何增强可视光波释放效果，汤斯和阿瑟·肖洛对可行性条件进行了阐述。

For example they can force light to skirt along the outside of an object, hiding it from view as if behind an invisibility cloak.

比如说，它们可以让光波绕开一个物体外围，就好像隐藏在一个隐形斗篷后面，让人无法看到它。

Well, it's kind of similar with light, except that the frequency of a light wave determines its hue, while the amplitude relates to its brightness.

嗯，这和光有点相似，只是光波频率决定了它色调，而振幅与它亮度有关。

This was due to the reflecting power of the walls of ice, which threw the beams of our beacon right back at us.

那是四面冰墙强烈反射，把探照灯光波猛烈反射进客厅中来。

Together, these cones can sense millions of different color combinations based on the mixture of light waves your cones are picking up.

这些锥体细胞可以感知数百万种不同颜色组合，基于你锥体细胞接收到光波混合。
