Radiação Térmica E a Fórmula De Planck

Abstract

THERMAL RADIATION AND PLANCK’S FORMULA. In this paper, theoretical and experimental research on blackbody thermal radiation is discussed and historically ordered. The main thermal radiation equations following Planck’s revolutionary idea are obtained using the formalism of statistical mechanics. These equations, already well known, are deduced in a very detailed and didactic way in order to facilitate the reader’s understanding. The consequent results of Planck’s formula for blackbody radiation are analyzed: the limits of the average energy for frequencies tending to zero and infinity, Stefan’s law and Wien’s displacement law.

Quantum Physics in the Context of Countable and Uncountable Infinite Sets from the Perspective of Real Analysis

“…In 1900, German physicist Max Planck published his theory on the quantization of light energy to explain the problem of blackbody radiation, which had been a subject of much discussion since it was first observed by Gustav Kirchhoff in 1860 [15]. Planck's theory, known as the Planck equation, was able to successfully describe the phenomenon of blackbody radiation emission through a revolutionary approach [16]. According to Planck, the energy 𝐸 of standing electromagnetic waves that oscillate sinusoidally with time is a discrete quantity rather than a continuous one [17].…”
