The analysis

The claim is a standard piece of physics common knowledge taught in introductory and advanced electrodynamics courses (derived as c = 1/sqrt(mu_0 * epsilon_0) directly from Maxwell's equations). None of the retrieved papers specifically test or contest this textbook derivation; rather, they are modern applied physics and chemistry studies. Therefore, it falls under COMMON_KNOWLEDGE.
