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.On Thursday, June 5, 2025 at 11:19:09 PM UTC-6 Brent Meeker wrote: On 6/5/2025 8:37 PM, Alan Grayson wrote:On Thursday, June 5, 2025 at 9:17:34 PM UTC-6 Brent Meeker wrote: On 6/5/2025 6:57 PM, Alan Grayson wrote:On Thursday, June 5, 2025 at 2:53:01 PM UTC-6 John Clark wrote: On Thu, Jun 5, 2025 at 1:35 PM Alan Grayson <[email protected]> wrote: /> The frequency is just a number that defines a photon's energy. 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
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.
