CLASSICAL DERIVATION OF PLANCK'S RELATION AND CONSTANT THROUGH THE POYNTING VECTOR

Planck’s relation E=hv establishes a direct proportionality between the energy of a photon and the frequency of the electromagnetic wave. In the conventional framework of quantum mechanics, Planck’s constant is introduced as a fundamental constant. Its value is determined experimentally and accepted as a starting point. In this work, however, it is shown that the relation E=hv, and thus Planck’s constant h, can be derived using classical electromagnetic theory.
