electromagnetic spectrum

基本解釋

The material could be applied to all parts of the electromagnetic spectrum, meaning it could be used to make materials invisible to radar.
這種材料可以應(yīng)用到電磁波譜的所有波段，這就意味著它可以用來(lái)讓雷達(dá)對(duì)材料“毫無(wú)察覺(jué)”。
They suggest that any alien civilisation worth its salt would alight not on the photons of the electromagnetic spectrum—whether optical or radio-frequency—to send messages to other solar systems.
他們指出，任何有頭腦的外星文明都不會(huì)發(fā)射電磁波譜中的光子——無(wú)論是可見(jiàn)光波段還是射頻波段——曏另一個(gè)太陽(yáng)系傳送信息。
By deflecting certain parts of the electromagnetic spectrum, an image can be altered or made to look like it has disappeared.
通過(guò)扭曲電磁頻譜的某一部分，就能夠改變一個(gè)影像，或者讓影像看起來(lái)像消失了一樣。

So, our detection devices are a little bit limited here today, we're actually only going to be using our eyes, so that means that we need to stick with the visible range of the electromagnetic spectrum.
我們今天所有的探測(cè)儀器十分有限，實(shí)際上我們要用我們的眼睛來(lái)觀測(cè)，這意味著我們衹能看到,電磁譜中的可見(jiàn)光區(qū)間。
