4) Nyquist Limit
Here we have a static charge radiating.
Since it is not pulsating, there is no
frequency limit for its radiation.
Here we have an electron pulsating 3X times
faster than the movement frequency. The
radiation is generated no problem.
Here we have an electron pulsating at the same
frequency as the movement frequency. Only the
peaks are generated. No valleys. So the radiation
at the movement frequency is not generated.
This frequency is not generated because of the
