After writing a paper critical to Maxwell’s electromagnetic theory, it is only natural to continue with an article critical to Hertz’s work. This is because every physics textbook today claims that Hertz demonstrated experimentally Maxwell’s theory. This claim amounts to saying that Hertz demonstrated experimentally that radio waves and light are electromagnetic, i.e. that they are made up of entangled electric and magnetic fields that oscillate and induce one another. In this work it will be shown that Hertz’s claim of having verified experimentally Maxwell’s theory is an exaggeration simply not true. Although Hertz did confirm the existence of a certain wave propagating in air, it cannot be said that his verification that the waves were composed of magnetic and electric oscillations is correct. And Hertz explicitly stated that he did not offer a direct verification that light itself is electromagnetic. I only wish more physicists read Hertz’s works before believing Maxwell’s theory or that it has been confirmed experimentally through Hertz’s works or otherwise.
