*Nothing? Nothing at all? Not quite.There is a
simple equation that shows the relationship between
the frequency of light, its wavelength and its
speed, its c=λ⋅f. And because of that very simple
relationship you can easily perform a fun
experiment at home:*

and a chocolate bar

***If frequency and wavelength are just numbers and
have no relationship with physical reality then I
don't see how you could use them to calculate the
speed of light which most certainly does have a
relationship with physical reality.*
*As far as I know, it's never been shown that photons
have spatial extent. So, the frequency and wavelength
are just numbers that allow us to calculate a photon's
energy. AG*
You're directly measuring the wavelength. The speed of
light is just a conversion constant. So you're
inferring the frequency of the microwave.

*Then the photon has extention in space? Is this your claim? AG*
*No.
Brent*
So we're in agreement, and therefore the frequency and wavelength
of a photon do not correspond to any extention in space as those
parameters usually do. AG
I didn't say that, I said they wasn't what I was claiming above
your query. Obviously wavelength is an extension in space and
frequency is the inverse of a time period. Physically these
exhibited by things like the chocolate bar in the microwave and
more commonly by the design of antennae and resonators.
As for lateral extension, normal to the direction of propagation,
I think that's quantum, i.e. a probabilistic distribution that
depend of the emitter.
Brent
If I understand basic English, you agreed that there's no evidence
that photons have spatial extention. Antennae work because of the
ensemble property of photons.
But they are scaled to wavelength. And it's the wavelength that
determines the standing waves in you microwave and makes the chocolate
bar test work.
As for Relativity and half-lives, it's easy to speak as if one knows,
but the core question remains unanswered. If an external observer
uses the LT to predict a dilation of the half-life of a muon, how is
that result physically possible if the muon's clock in its own frame
remains unchanged? AG
Because two clocks moving relative to one another don't agree on the
direction of "future" in spacetime.
