The formula tells us or absorbed based on the energy difference between the two levels that we're going between, that the electron is transitioning between.

这些公式告诉我们,或发出的光的，频率大小,是基于，电子转移的，两个能级，之间的能量差。

That energy will be absorbed by the hydrogen atom, n=1 the electron will rise from n equals one n=2 to n equals two.

这能量将会被氢原子吸收，这个电子会从,上升到。

And what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.

我们预测，两个能级之间的能量差，我们知道，它要么和发出的光有关,如果它发出光子的话，要么它吸收光子,从低能级跃迁到，更高能级上去。

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。
