The flicker will be 12 Hertz (as opposed to 120Hz at full power). You
don't have to skip whole cycles; half-cycles will do. The polarity doesn't
matter for a resistive load.


** Skipping half cycles means you are loading the supply for half cycles -
this creates a DC component on the supply.

Very bad idea.

Seems to me that if you have a reed vibrating at 440 cycles per second, and another reed vibrating at 442 cycles per second, you can't measure the observed phasing of those notes in Hertz as well, hence the use of the other phrase. ...

    ... The hertz is what used to be called cycles per second; yes, you do find them in radios, but just rather more of them. ... If you make electrical signals oscillate a lot faster, they radiate more from the wires that are carrying them; once you get above a few hundred cycles per second (the electricity supply in aircraft is often 400 Hz rather than 50 or 60, for some reason - I presume to do with the speeds aero engines are normally run at), the oscillations tend to be created with electronics, rather than mechanical generators. ...
