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，光是在宇宙中穿梭微小磁波。

We should beware of the electromagnetic waves from the computer.

我们应该小心从脑中发射磁波。

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网络使用磁波，但是在水中它们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”出现为任何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，以致于它们使用是比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.

他们为报中磁波研究作出了贡献，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.

我们可以藉由缩小磁波波长来解决问。

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

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磁波是何穿越空间。

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，辐射利用磁波。

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

“X 射线” 是一种高能磁波。

Instead, heat is transferred by electromagnetic waves.

相反，热量是通过磁波传播。

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

金属也可能是个问，因为它非常擅长反射磁波。

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——同磁波相似。

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