Electromagnetic waves can have all sorts of strange effects on us.

对我们有各种各样奇怪的影响。

Infrared waves are electromagnetic energy that cannot be seen with the human eye.

红外线是肉眼看不到的。

We should beware of the electromagnetic waves from the computer.

我们应该小心从脑中发射的。

To see something, we need light, an electromagnetic wave.

想要做观测，我们需要光，也就是。

Light is basically a tiny electromagnetic wave traveling through space.

基本上，光是在宇宙中穿梭的微小。

Radio waves have the longest wavelengths in the electromagnetic spectrum.

无线在谱中长最长。

So small that the electromagnetic waves we used to see are too big to touch them.

它小到我们过去所能看到的根本碰不到。

Ten-second trivia: What type of waves have the longest wavelengths in the electromagnetic spectrum?

在谱中哪种具有最长的长？

The oven emits microwave radiation, which is absorbed by the molecules, especially those of water.

微炉放射出 被分子吸收，尤其易被液体吸收。

We can try to solve this by creating electromagnetic waves with more and much smaller wavelengths.

我们可以藉由缩小长来解决问题。

Now, a new generation of wiring can direct the energy on one part of the brain.

今，新型线可将直接送至大脑的某一区域。

With wavelengths measuring between one millimeter and 62 miles, radio waves are the longest.

无线的长在1毫米至62英里之间，是其中最长的。

But together, we call all of these different kinds of light the electromagnetic or EM spectrum.

但是我们把所有这些不同种类的光统称为或谱。

Wifi networks on land use electromagnetic waves, but in water these will only travel a few centimetres.

地面上的WiFi网络使用，但是在水中它们只能穿行几厘米而已。

Both brain and radio waves are forms of electromagnetic radiation, waves that travel at the speed of light.

大脑和无线都是一种，即以光速传播的。

The advent of " metamaterials" provides a new solution for the perfect invisibility of any electromagnetic wave.

“超材料”的出现为任何的完美隐形提供了新的解决方案。

Now, as these two oscillating fields move across space, that is what is known as an electromagnetic wave.

现在，当这两个振荡场在空间中移动时，这就是我们所说的。

Maybe as civilizations develop, they quickly discover communication technologies far more sophisticated and useful than electromagnetic waves.

可能一个文明发展得太快，以致于它们使用的是比更加复杂有用的信号。

They give tribute to electromagnetic waves of the telegraph, a new form of communication at the time.

他们为报中的研究作出了极大的贡献，也就是当时新的一种通信方式。

To understand what's actually happening here, we need to understand how electromagnetic waves like light travel across space.

为了理解这里到底发生了什么，我们需要理解像光这样的是何穿越空间的。
