When you tune a radio to a station, you pick up the information that is being sent out via electromagnetic waves at a particular frequency —— in this case they are radio waves.

当你转到一电台频道，你收到讯息其实是来自接收特定频率电磁波，在这称它为“无线电波”。

In order for our atmosphere to absorb any kind of radiation, it needs to have some electrically charged particles for passing electromagnetic waves to push around.

为了使够吸收任何种类辐射，它需要有一些带电粒子，以便通过电磁波来推动。

Albert Einstein demonstrated that light, which had previously been considered an electromagnetic wave, must also act as a particle, localized in packets of energy called photons.

阿尔伯特·爱因斯坦证明，以前被认为是电磁波光，也必须扮演粒子角色，被定位在称为光子量包中。

" The real 'perfect invisibility' requires that the above detection means can be avoided, and its essence is the low detectability of any electromagnetic wave, " Chu added.

“真正‘完美隐身’要求可以避开上述探测手段，其本质是任何电磁波低可探测性，”褚补充道。

It involves a vacuum-sealed pod that rides on top of electromagnetic waves, very simply, this is sort of similar to the way a surfer's board rides ocean waves.

它包含一个位于电磁波顶部真空密封舱，简单来说，就像冲浪者冲浪板一样，在海浪中航行。

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。

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，但是在水中它只穿行几厘米而已。

Sunlight is composed of electromagnetic waves and is our primary source of ultraviolet radiation, which has a shorter wavelength than visible light and carries more energy.

太阳光是由电磁波组成，也是接收到紫外线主要来源，它有相较可见光更短波长 也带有更多量。

It is a man-made composite material that changes the conventional properties of light and electromagnetic waves by designing and reorganizing the fine structure of the material.

它是一种人造复合材料，通过设计和重组材料精细结构，改变光和电磁波传统特性。

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，这就是所说电磁波。

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

它小到过去所看到电磁波根本碰不到。

Cell phones connect to networks by emitting information in the form of electromagnetic waves, specifically radio waves, which occupy this band of the electromagnetic spectrum.

手机通过以电磁波形式发射信息连接到网络，特别是无线电波，它占据了电磁频谱这一频段。

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，需要理解像光这样电磁波是如何穿越空间。

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

“超材料”出现为任何电磁波完美隐形提供了新解决方案。

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

可以藉由缩小电磁波波长来解决问题。

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

可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。
