Yes. The short journey was described by the term "dt". According to
Cecil, that is the amount of time after energy is reflected and before
it 'turns around and goes the other way as it is required to do by the
law of conservation of energy'. You may recall that it is forced to go
the other way 'because there are only two directions in a transmission
line'.

So you don't even accept differential calculus? :-)
Jim, you have never answered the tough questions so I
will keep asking. I just posted an example with one
question that should be easy for you to answer.

In the example, what happens to the energy and momentum
in Pref1 when the load is switched from 300 ohms to 50
ohms? It's a simple question. Please be specific in your
answer.
