Standing-Wave Current vs Traveling-Wave Current

So I cannot display current phase vs length? No wonder
Roy is so confused about the nature of current phase.
Seems I have to paste the current phase into EXCEL
just to get a decent graph of it.

Standing-Wave Current vs Traveling-Wave Current
 

Humph, all this hot air just addles my aged brain...

I do know a FEW things however...

I know that standing waves exist because I can slide my fluorescent
bulb along the line and show precisely where they are

I can measure the distance between peak voltage points with a metric
wooden ruler and demonstrate/prove that 3X10^6meters / Fcycles =
the length of the measured 2 radians of travel....

But most importantly I KNOW that the standing waves are real and have
energy because my fluorescent tube lights up as it passes the peaks...
That requires energy/watts/joules to flow through the gas of the
tube...

You can use all the damned words in the world to talk around and
obscure the subject, but when I slide along my line the bulb lights to
maximum brilliance every half wave length of the standing waves...

But what does it mean at the other places along the line where
the bulb does not light?

Does it mean that there is no energy at these points on the line?

If it was a conscious design, I apologize for saying it is
a bug. So how can I display a 2D graph of phase vs segments?

Ofcourse not!.
The energy is directed else where, it usually changes to heat.
As I have stated before, in a tank circuit the resistance in the
circuit
also is cyclic with respect to energy distribution. Where there is
resonance
the resistance factor is quite small. As one moves to the "near
stable"
position the resistance factor becomes larger with respect to energy
distribution.
If you wish to pursue what is happening in such a circuit then break
up the application
of voltage in consequitive steps to see the rotational effects of
capacitor and
inductance energy discharge together with the energy distribution when
the
voltage drop over the energy storage units are equal.

Fluorescent bulb or neon bulb respond, are fired, by voltage being higher.
Where the voltage is high, the current is low and vice versa (standing
waves).
Energy is the same along the antenna, just standing waves exhibit max and
min according to distribution of current or voltage along the radiator.

If W8JI, W7EL and their followers moved neon bulb along the loading coil,
they would see the change in brightness along the coil (getting brighter
closer to the top) indicating diminishing current along the same length.
Ergo (standing wave) current is not constant along the loading coil as they
tried to convince their followers to the contrary.

One can just look at the standing wave current equation and
tell it is not constant. The standing wave current varies
with location on the antenna.

Nice graphic, Cecil.. But the thread has drifted beyond recognition..
Part of the original dispute across a couple of threads as I
remember it, was the contention that there is no energy contained
within the reflected wave and therefore no energy contained within the
standing wave, i.e. a mere artifact...
I simply wanted to point out that the standing wave on a line does
contain energy and it is a childishly simple exercise to prove it,
therefore the reflected wave must contain energy...
As far as the questioner, where does the energy go between the
standing wave peaks - oy vey....
If it is a real question - as opposed to a rhetorical device which I
hope was the intent - then the profound ignorance of basic physics is
vastly beyond the limited space I have to go over it... See ANY
introductory level, physics textbook for details...

the REAL answer is that the 'standing' wave is a creation of experimenters
100 years ago who didn't have the impedance, current, and voltage
measurement tools we have today, and didn't know of or understand
superposition. 'standing' waves are nothing but a result of superposition
of the forward and reflected waves, they have no physical significance
beyond that. it is worthless to talk about power or energy in them since
they can always be broken down into the component waves which make more
sense to work with.
