*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:*

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.
