While devices like the NIST-F1 use atomic signals of microwave frequency with billions of cycles per second, newer clocks, including Oates’, rely on light waves beating a million times faster.

诸如NIST-F1的仪器运用的原子信号是频率为数十亿赫兹的微波，新式时钟包括奥茨的都是运用频率快上百万倍的光。

With the increasing of the period, microwave frequency decreases.

随着周期的增大，微波频率降低。

So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.

重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。

Congestion is inevitable because Wi-Fi uses the same unregulated 2.6 gigahertz frequency as microwave ovens, cordless phones and the upcoming Bluetooth networking standard, which lets phones, PCs and vending machines talk to one another.

FORBES: Digital Spin

Yet despite high costs of entry and regulatory limits on spectrum availability and infrastructure investment, new technologies (LTE, satellite, microwave, and higher-frequency communications) and new competitors continue to enter the market all the time.

This frequency is crowded since it is used by everything from other tablets to microwave ovens, baby monitors, Bluetooth devices, not to mention the neighbors' Wi-Fi networks.
