Then they use radio frequency energy to heat the tissue around the catheter.

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。

McDonald was also the third physician in the world to perform a procedure called conductive keratoplasty -- a noninvasive surgery for farsightedness that involves using radio-frequency energy to heat small spots around the cornea.

Then, the waves' frequency is tweaked and the sample blasted head-on in order to heat it.
