Is there a "standing wave" along the secondary? Not really - Most TCs
are best modeled as a lumped LC of some sort.
There is a (much discredited) theory that because a TCÂ behaves like an
unterminated 1/4 wave transmission line, or a 1/4 wave loaded antenna
(both of which would have high voltage at the unterminated end). That
theory was reinforced because many TCs happen to have about 1/4
wavelength of wire on them (especially longer skinnier ones), by
coincidence.
It turns out, though, after extensive modeling and analysis, with lots
of measurements by folks on the list that a lumped model works best.
Sure, you can use a fancier model of coupled segments of transmission
lines, just as you can use a 9th order polynomial to represent a
straight line with some noise on it, but that doesn't mean that the 9th
order polynomial is a better fit to the underlying physics.

No.

Not sure what a T-wave is.

Not a problem.. just be aware that Tesla and things Tesla related seem
to attract a lot of cranks. The guy was brilliant, invented a lot of
useful stuff, had a lot of odd ideas that anticipated modern
developments, and was sort of a prototype of the "mad scientist". So
there are people who try to read more into what Tesla did and said than
actually is justified. Tesla proposed some things that are desirable,
but are now known to be impossible. Were Tesla alive today, I suspect
he would modify his ideas and theories to accommodate the current state
of knowledge.
