Eli5: What does the frequency (Hz) have to do with electrical output? If the world has 50/60 Hz frequency for their outlets, what exactly does that mean/do? Is it as simple as if it goes below/exceeds the specified frequency it just gives/reduces power output or something different?

The Hz tells you the frequency that the Alternating Current is alternating at. Think of DC current as a constant push, while AC current is going “push, pull, push, pull, etc.” very quickly. Something like an incandescent lightbulb probably doesn’t care too much what frequency current it’s getting, but something like your laptop has to convert that AC into DC for the computer to use. Feeding it the wrong frequency would likely break something very quickly.
