So the speed of a sub atomic photon is not C?
How fast do photons go in a vacuum?
Aren't photons light particles?
What is a light wave made of?
What exactly is light?
Don't you just love physics?

Hello MJA:
It has nothing to do with any of the above thoughts. It has to do with making a good measurement.
Resolution plus stability = accuracy.
(Stability = + or -) a fluctuation in terms of the
resolution = (what can be resolved)
The wave is simply much more stable (repeatable) so is used as the method indicated as the standard method to measure C.
This is very basic metrology. It is also why Dave as a metrologist gets frustrated when the basics of his profession are not understood.
