So my OP is correct.
the thermal energy that the sun radiates is a combination
of the heat that is generated by the continuous processes
that occur within the sun.
also the heat that a process generates does not appear in
its highest magnatude suddenly ...
the thermal heat continuously builds and then falls in magnitude.and it is the continuous building and falling of the
radiated thermal energy that results in what we detect
as the electromagnetic spectrum.
and that the transmission of the entire spectrum of those sun
generated electromagnetic waves are contained in a continuous
wave with frequencies that range from the shortest wave to the longest
wave then from the longest wave to the shortest wave.
like copying the below image and flipping it horizontally
and placing the two images side by side with the two
long waves facing each other.
