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

磁波对我们有各种各样奇怪的影响。

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

想要做观测，我们需要光，也就是磁波。

Light is basically a tiny electromagnetic wave traveling through space.

基本上，光是在宇宙中穿梭的磁波。

We should beware of the electromagnetic waves from the computer.

我们应该心从脑中发射的磁波。

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

它到我们过去所能看到的磁波根本碰不到。

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

地面上的WiFi网络使磁波，但是在水中它们只能穿行几厘米而已。

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，以致于它们使的是比磁波更加复有的信号。

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

他们为报中磁波的研究作出了极大的贡献，也就是当时新的一种通信方式。

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

“超材料”的出现为任何磁波的完美隐形提供了新的解决方案。

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磁波是如何穿越空间的。

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，这就是我们所说的磁波。

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

我们可以藉由缩磁波波长来解决问。

Conduction is the transfer of heat between solid objects, convection uses the movement of fluids, while radiation relies on electromagnetic waves.

传导指的是两个固体之间热量的转移，对流运流体的运动，辐射利磁波。

Because it's also useful in studying curves, pi helps us understand periodic or oscillating systems like clocks, electromagnetic waves, and even music.

因为学习曲线也需要到 π，π 帮助我们认识周期或振动系统，如钟摆、磁波甚至音乐。

Metal can also be a problem, because it’s really good at reflecting electromagnetic waves.

金属也可能是个问，因为它非常擅长反射磁波。

“X 射线” 是一种高能磁波。

Gravitational waves—ripples in the geometry of space-time—are analogous to electromagnetic waves.

引力波——空间-时间几何形态的波动——同磁波相似。

Instead, heat is transferred by electromagnetic waves.

相反，热量是通过磁波传播的。

There's actually higher frequencies of electromagnetic waves that have all sorts of applications.
