I said you, "mismatch" it is a magical word. TL reflected waves also
are explainabe with "mismatch" word. However mismatch it is a name for
a physical phenomena, what is that?

Water/Air
Most people would agree that both are physical.

When we talk about a traveling
wave

Hi Miguel,

Who is "we?" *"Traveling Waves" have their own special meaning, and
that meaning is unnecessary for this discussion.

reaching the "mismatch" point we

We?

can try to explain WHY the
reflection occur.

If you choose, but the WHY is unnecessary too.

Skip the magic words, as you call them. *Everything you discuss is
available, by parts, but together nothing changes anything.

A transmission line is an artificial medium. *It is artificial in the
sense of being man-made. *Being artificial, it attempts to be similar
to nature's available media. *The electronics is same for all.
Discontinuities, interfaces, abound in both artificial realms and
natural realms. *Their behavior is governed by the same physics - only
the parameters are different (which is the nature of reality).

Good mornig Richard

You are right my friend, there are not conduction currents, there not
displacement currents, there are not electrical and magnetic fields,
there are not electric charges neither electrical dipoles in soil and
water, just "mismatch" and "discontinuities" (do explain antenna
radiation with "mismatch") I wonder why those evil teachers make me
spend my time studying those things. Well... now I will return to my
science fiction physics books
