Both Wi-Fi and Li-Fi transmit data over the electromagnetic spectrum, but whereas Wi-Fi utilizes radio waves, Li-Fi uses visible light.

Wi-Fi 和 Li-Fi 都通过电磁频谱传输数据，但 Wi-Fi 使用无线电波，而 Li-Fi 使用可见光。

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.

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

So friction and other forces heat the material falling in to millions of degrees, so hot that it blasts out light across the electromagnetic spectrum.

所以摩擦和其他力会把物质加热到几百万度，热到能在电磁波谱中释放出光。

Objects actually radiate energy that covers a whole range of frequencies on the electromagnetic spectrum – all different kinds of light.

事实上，物体发出的能量包括电磁波的所有波频率——所有不同类型的光。

We investigated the different types of waves on the electromagnetic spectrum as well as how to calculate the amount of energy they can carry.

我们研究了电磁波谱上不同类型的波，以及如何计算可以传输的能量。

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.

手机通过以电磁波的形式发射信息来连接网络；具体来说， 无线电波占据电磁频谱的这个频段。

But while dark matter may not be visible in the electromagnetic spectrum, it’s still matter, so we should be able to measure its interactions with other matter.

但是， 虽然暗物质在电磁波谱中可能不可见，但它仍然是物质，因此我们应该能够测量它与其他物质的相互作用。

Telescopes from across the electromagnetic spectrum -- for example, the proposed NASA facility, the STROBE-X X-ray space telescope -- can help us potentially determine what exactly dark matter is.

来自整个电磁波谱的望远镜——例如，拟议中的 NASA 设施，STROBE-X X 射线太空望远镜——可以帮助我们确定暗物质究竟是什么。

But the visible light we're able to see is only a tiny chunk of the full electromagnetic spectrum, which ranges from short gamma and X rays all the way to long radio waves.

但是我们能看到的可见光只是整个电磁波谱的一小部分，从短伽马射线和 X 射线一直到长无线电波。

Using light offers the possibility of breaking out of this conundrum by exploiting a completely different part of the electromagnetic spectrum, one that is already ubiquitous because it is used for another purpose: illumination.

运用一个完全不同的电磁波段——可见光，就有可能解决这个难题；这个波段其实早已相当常用，因为它有另一个作用：照明。

The same way we observe visible light from celestial objects using our eyes and optical telescopes, we can also take advantage of the other parts of the electromagnetic spectrum in astronomy.

就像我们用眼睛和光学望远镜观察天体发出的可见光一样，我们也可以利用天文学中电磁波谱的其他部分。

The latest generation of solar panels are not only cheaper and more affordable than ever, they can also access a wider part of the electromagnetic spectrum—beyond visible light, into the infrared.

最新一代的太阳能电池板不仅比以往更便宜、更实惠，而且还能够利用更宽的电磁波谱部分——超越可见光，进入红外线。

However, Dyson also believes that most known substances that would make up a Dyson Sphere would be re-radiating energy in the infrared part of the electromagnetic spectrum, which was not being detected with our mysterious star.

然而，戴森还认为，大多数已知的能组成戴森球的物质，将在电磁波谱的红外部分重新辐射能量，而我们的这颗神秘恒星没有被探测到。
