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.

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

Well, I am just sitting here with this 120,000 gauss magnet in my hand
and a magnifying glass in the other--attempting to see the photons
shooting from one side of the magnet to the other ... I'd at least think
the dern photons excite the gas and would light up the neon bulb I am
holding next to one side!
