EM waves are sets of coherent photons.

Cecil:

I composed this thread with you in mind.

Welcome back from retirement. The level of argument you bring was
sorely missed. :-)

This is actually a good one. Planck, Newton and Feynman ... and missing
quotations, nuclear emissions and internet arcana. Hello to Richard,
Cecil and the rest and thanks for an enjoyable thread.

PS, from a non-physicist perspective, "duality" is a concept that is fun
to debate. There might be extra innings.

For some individuals, it is a thorn in the side. :-)

So Cecil , what should I call incoherent photons?
and welcome back

Anyway, back at the ranch, no one has brought up quantum
electrodynamics (Feynman would be unhappy - since all the photons
leaving the surface of the white hot, rotating, razor blade will
occupy all possible paths from there to your eye - including having
all of them emanate only from the razor's edge for an instant)

And, no one has invoked Schroedinger since looking at that photon will
cause it to disappear...

Now, let me discuss Alice - had Alice taken more of the potion and
grown large enough that the lens and retina of her eyes were millions
of 80 meter wavelengths across, she would indeed see your antenna glow
with pulses of 'light' as you key your transmitter, dit dit dit
dahhhhhh...

Speaking of which, I now feel the urge to put Beethoven's Fifth on the
turntable...

I'm not sure but I'm pretty sure you cannot
call them a single wave (function).

I prefer Glenlivet's fifth on my table.

Ahhha, so that's where the incoherent photons come from!
