Incandescent bulbs like that in the picture don’t really flicker. They might pulsate a little bit but even at their faintest they would still have significant light output.
Some LED bulbs do flicker though, it depends on how they implement the AC to DC conversion. If they flicker, it is easily noticeable to the human eye, especially when looking at motion.

It has a 60Hz electric waveform in, and it produces visible light, which is in part a ~500THz wave.
