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?
