However, radio waves from Venus are similar to those emitted during terrestrial lightning storms.

然而，来自金星无线电波与地球上雷暴释放电波似。

But to see one, you would need to build a telescope as large as the Earth, because the black hole that we're looking at gives off copious radio waves.

但是想要亲眼所见，就需要建造一个和地球一样大望远镜，因为我们所看到黑洞会释放出大量无线电波。

With wavelengths measuring between one millimeter and 62 miles, radio waves are the longest.

无线电波波长在1毫米至62英里间，是其中最长电磁波。

Radio waves also travel at the speed of light, and assuming such an automatic messenger picked up our first broadcasts of the 1920's, the message to its home planet is barely halfway there.

无线电波也是以光速。假定外星人这种自动化信息装置接收了我们二十世纪二十年代第一广信号，那么这个信号在发回到原来行星途中刚刚走了一半路程。

Compare that to AM radio waves, which are hundreds of meters long.

下，AM无线电波有几百米长。

Scientists first discovered Lake Vostok in the 1970s by using radio waves that penetrate the ice.

20 世纪 70 年代，科学家们通过穿透冰层无线电波首发现了沃斯托克湖。

For this he and his wife received the Nobel Prize for physics in 1910, and did so again in 1912 for their work on very high frequency radio waves.

为此，他和妻子在1910年获得了诺贝尔物理学奖，1912年由于在非常高频广波段方面研究，再获得了诺贝尔奖。

Beyond particles, electromagnetic radiation, from x-rays to radio waves, exists everywhere.

除了粒子，电磁辐射，从 x 射线到无线电波，无处不在。

They had used the telescope to study radio waves from distant planets.

他们此前曾用该望远镜来研究遥远行星发出无线电波。

Radio waves have the longest wavelengths in the electromagnetic spectrum.

无线电波在电磁波谱中波长最长。

And when they do that, it leaves less room on the wireless spectrum, the radio waves that these technologies use are limited.

当他们这样做时，就会在无线频谱上留下更少空间，这些技术使用无线电波是有限。

Each spacecraft uses radio waves to beam the time and its position to Earth.

每颗卫星都使用无线电波向地球发送时间和位置信息。

Sometimes you don't even need an orbiting star at all, and just the x-rays and radio waves from the hot infalling material can be used to determine the mass of a solitary non-star object.

有时候，我们甚至根本不需要轨道上恒星，仅需要x射线以及来自热陨落物质电波就可以确定一个孤立非恒星物体质量。

Radio waves can now pass through both front and the back, resulting in improved cellular reception.

无线电波现在可以从正面和背面穿过，从而增强了蜂窝信号接受能力。

Similar to a radio, your cell phone receives signals at specific frequencies, but it can also transmit its own radio waves back to a network at the same time.

同广原理，手机接收属于特定频率信号，但它同时也能发送无线电波回一网路。

Star forming gas clouds emit a very narrow wavelength range of radio waves, and this could be used to measure their Doppler shift, how quickly they were moving toward or away from us.

恒星形成气体云发射出波长范围非常窄无线电波，这可以用来测量它们多普勒频移，即它们向我们移动或远离我们速度。

We don't have large-scale invisibility cloak technology yet, but scientists are working on a lot of different ideas, like creating flexible sheets of liquid metal that can block radio waves used in radar.

我们目前还没有大范围隐形斗篷技术，但是科学家们在努力，试验各种点子，例如制造可延展液态金属片，阻止雷达无线电波。

But now we want to equip base stations with both radar and communication functions so that when they become capable of communicating, the radio waves they transmit can also sense objects located a kilometer or even farther away.

但现在我们希望让基站同时具备雷达和通信功能，这样当它们进行通信时，所发射无线电波也能感知一公里甚至更远距离物体。

So you have radio waves and microwaves and X-rays and gamma rays passing through your body right now and you're completely unaware of it, because you don't come with the proper biological receptors for picking it up.

如果无线电波、微波还有X射线和伽玛射线正穿过你身体，你是完全意识不到它们存在。因为人类没有进化出 可以感知这些波生物感受器。

The growth in radio and television broadcasts—especially with digital and high-definition TV—now provides an enormous amount of high-frequency radio waves which are ideally suitable for passive radar systems.

现在无线电和电视广增长（尤其是数字电视和高清电视出现以后）提供了海量高频电波，这些非常适合用于被动雷达系统。
