But the visible light we're able to see is only a tiny chunk of the full electromagnetic spectrum, which ranges from short gamma and X rays all the way to long radio waves.

但是我们看的可见光只是整个电磁波谱的一小部分，从短伽马射线和 X 射线一无线电波。

And I got very excited, and I ran into my wife, she was in the next room at the time, listening to Conelrad on the radio, y'know.

In order for our atmosphere to absorb any kind of radiation, it needs to have some electrically charged particles for passing electromagnetic waves to push around.

为了使我们的大气层够吸收任何种类的辐射，它需要有一些带电的粒子，以便通过电磁波来推动。

Albert Einstein demonstrated that light, which had previously been considered an electromagnetic wave, must also act as a particle, localized in packets of energy called photons.

阿尔伯特·爱因斯坦证明，以前被认为是电磁波的光，也必须扮演粒子的角色，被定位在称为光子的量包。

" The real 'perfect invisibility' requires that the above detection means can be avoided, and its essence is the low detectability of any electromagnetic wave, " Chu added.

“真正的‘完美隐身’要求可以避开上述探测手段，其本质是任何电磁波的低可探测性，”褚补充道。

It involves a vacuum-sealed pod that rides on top of electromagnetic waves, very simply, this is sort of similar to the way a surfer's board rides ocean waves.

它包含一个位于电磁波顶部的真空密封舱，简单来说，就像冲浪者的冲浪板一样，在海浪航行。

You can see colors over an electromagnetic wavelength anywhere from 410 nanometers, here you'll find violet, to roughly 680 nanometers, the home of red.

人眼见电磁波在 410 纳米约 680 纳米之间的颜色，即从紫色红色。

Conduction is the transfer of heat between solid objects, convection uses the movement of fluids, while radiation relies on electromagnetic waves.

传导指的是两个固体之间热量的转移，对流运用流体的运动，辐射利用电磁波。

Shows were broadcast at specific times and if you weren't there on time, you missed it. Broadcasts disappeared into the ether.
