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。

It also can send out radio waves as radar.

它还可以作为雷达发送无线电波。

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。

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。

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。

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。

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。

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。
