I believe that a clear conclusion won't be possible.
Light, radiation and induction are subjects far away to
be clear enough.

My problem here is that I have no help from nobody.
First I have to analyse and think deep before I say something.
Then I have to reply at least twice, several post each day.
I'm tired and about to give up.

Nevertheless I can't give up because I love to learn and
I can't stop reasoning about the subject.

Now they bring up a new picture of radiation, with E and B
in phase, contrary to all that I've learn and understand so far
(curl E = - dB/dt). I have to digest that before I give a reply.

They also say:
«The field has one term which decreases as r^-2 and a second
term which decreases as r^-1. The former is the induction field.
It has a component in the direction of propagation (a longitudinal
wave). It dominates at small distances from the oscillator.
The latter is the radiated field (a transverse wave). It dominates
at large distances, and it has components which are at right
angles to each other and to the direction of propagation.»

My guess is that they start with Maxwell's equation
Curl E = -dB/dt decreasing as r^-2, and soon Maxwell's goes
to heavens and bring up new equations (???) where the
field decreases as r^-1 and a longitudinal wave turns out to
be a transverse wave without any justification.

There are so many underlying subjects that a little help will be
very appreciated.
