TL;DR

This paper derives Planck's blackbody spectrum within a classical framework by linking thermal scalar radiation and zero-point electromagnetic radiation, revealing a scale parameter related to experimental Casimir force measurements.

Contribution

It presents a classical derivation of the Planck spectrum incorporating zero-point radiation and introduces a scale parameter connected to cavity geometry and experimental data.

Findings

Classical derivation of Planck spectrum from scalar and zero-point radiation.

The scale parameter aligns with known physical constants like Planck's constant.

The approach connects theoretical classical physics with experimental Casimir force measurements.

Abstract

In this work we obtain Planck's blackbody spectrum from the thermal scalar radiation contained in a resonant cavity of volume V in the context of classical mechanics, which provides the classical zero-point electromagnetic radiation in terms of a scale parameter that depends on geometric properties of the enclosure and electrical magnitudes. The scale parameter of the classical zero-point electromagnetic radiation is associated to experimental measurements of Casimir forces, but we show that theoretically its value for known radiant cavities that approach a blackbody has a numerical value of the order of Planck's constant.
