ELI5: What are the differences between Hertz in electricity, in the electromagnetic spectrum, in processors, in displays and in sound?

Nothing.

A hz is a cycle per second.

If your screen is 120hz, then it refreshes 120 times per second.

If your power is 60hz (A/C) then it cycles 60 times per second

Your cpu does ghz or 1billion cycles per second. Each cycle is a chance to do something.
