electromagnetic spectrum

基本解释

The material could be applied to all parts of the electromagnetic spectrum, meaning it could be used to make materials invisible to radar.
这种材料可以应用到电磁波谱的所有波段，这就意味着它可以用来让雷达对材料“毫无察觉”。
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.
他们指出，任何有头脑的外星文明都不会发射电磁波谱中的光子——无论是可见光波段还是射频波段——向另一个太阳系传送信息。
By deflecting certain parts of the electromagnetic spectrum, an image can be altered or made to look like it has disappeared.
通过扭曲电磁频谱的某一部分，就能够改变一个影像，或者让影像看起来像消失了一样。

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.
我们今天所有的探测仪器十分有限，实际上我们要用我们的眼睛来观测，这意味着我们只能看到,电磁谱中的可见光区间。
