    Revisiting the Planck/Einstein Formula: A Critique of E = hf and Its Implications for Redshifted Light

    Revisiting the Planck/Einstein Formula: A Critique of E = hf and Its Implications for Redshifted Light We start by reviewing how light is generated in classical electromagnetism. Consider a flow of electrons in a metal (e.g., tungsten) approaching an atom, Fig. 1. Between the flow of electrons...
