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

电磁波对我有各种各样奇怪。

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

想要做观测，我需要光，也就是电磁波。

Light is basically a tiny electromagnetic wave traveling through space.

基本上，光是在宇宙中穿梭微小电磁波。

We should beware of the electromagnetic waves from the computer.

我应该小心从电脑中发射电磁波。

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

它小到我过去所能看到电磁波根本碰不到。

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

地面上WiFi网络使用电磁波，但是在水中它只能穿行几厘米而已。

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

“超材料”出现任何电磁波完美隐形提供了新解决方案。

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，以致于它使用是比电磁波更加复杂有用信号。

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

电报中电磁波研究作出了极大贡献，也就是当时新一种通信方式。

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

我可以藉由缩小电磁波波长来解决问。

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，这就是我所说电磁波。

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

了理解这里到底发生了什么，我需要理解像光这样电磁波是如何穿越空间。

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

传导指是两个固体之间热量转移，对流运用流体运动，辐射利用电磁波。

An " X-ray" is an electromagnetic wave of high energy.

“X 射线” 是一种高能电磁波。

Instead, heat is transferred by electromagnetic waves.

相反，热量是通过电磁波传播。

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

金属也可能是个问，因它非常擅长反射电磁波。

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

引力波——空间-时间几何形态波动——同电磁波相似。

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

实际上，更高频率电磁波具有各种各样应用。

Both are types of signals made up of electromagnetic waves that a radio can pick up.

两者都是由无线电可以接收电磁波组成信号。

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

因学习曲线也需要用到 π，π 帮助我认识周期或振动系统，如钟摆、电磁波甚至音乐。
