Nothing to do with an extended wave.* *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:* *Measuring the speed of light with a microwave oven and a chocolate bar <https://www.fizzicseducation.com.au/150-science-experiments/light-sound-experiments/measure-the-speed-of-light-with-chocolate/> * *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. Brent *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. 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?
