In a way, detectors like LIGO are big gravitational wave radios.

某种意义上说，LIGO 这类探测器，如同一台大型引力波收音机。

Radar is a device that sends out radio waves for finding the position and speed of a moving object such as a spy plane.

雷达是一种发射出无线电波以对目标（如侦察机）进行定位和测速的装置。

Beyond the spectrum of light your eyes can see, massive radio waves as wide as houses carry information between computers, GPS systems, cell phones, and more.

超过你肉眼可见的光谱范围，与房屋一样宽的无线电波使信息在电脑、GPS、手机等设备间传输。

It also can send out radio waves as radar.

它还可以作为雷达发送无线电波。

You might have heard things like infrared, or radio waves.

您可能听说过红外线或无线电波之类的东西。

For nearly two years, the spacecraft generated VLF radio waves that knocked energetic particles down into Earth's atmosphere.

在近两年的时间里，该航天器发出了甚低频无线电波，将高能粒子撞击到地球大气层。

One problem is that radio waves from these far away objects, even though they can get through, are extremely faint.

一个问题是， 来自这些遥远物体的无线电波即使可以通过， 也非常微弱。

Earth's magnetic field would cause the resulting barium ions to spiral, generating an electric current that could, in turn, produce electron-precipitating radio waves.

地球磁场会导致产生的钡离子呈螺旋状，从而产生电流，进而产生电子沉淀无线电波。

Each observer could use radar to say where and when an event took place by sending out a pulse of light or radio waves.

每个观察者都可以使用雷达通过发出光脉冲或无线电波来判断事件发生的地点和时间。

These signals are then picked up by the tower closest to them, which converts the radio waves into a digital electrical impulse and passes it along to a hub of the network called a mobile switching center.

这些讯号由最接近的基地台接收，并将无线电波转换成电子讯号，再传送到名为“行动交换中心”的网路枢纽。

Some very important discoveries have been made by this technology, especially you consider that some objects in space give off radio waves but don't emit any light.

这项技术已经取得了一些非常重要的发现，特别是你认为太空中的一些物体会发出无线电波但不发出任何光。
