This applies to all forms of EM energy, so let's calculate the 'step

000 0066 joules - which is unimaginably small.

Maybe 40 nano-eV is more imaginable? :-)
For me, it is a lot easier to visualize a cloud
of photons leaving an antenna than it is to visualize
the field lines closing upon themselves (like a soap
bubble) and breaking free of the antenna.


Each to his own imagination. I'd find it hard to keep track of all
10^(30) photons emitted from here this weekend... though some of them
will probably send postcards :-)


Incidentally, your above number is off by 0.3% :-)

Well, imagine that!
