Paperback. Condición: New. Print on Demand. This book delves into the fascinating world of the photoelectric effect, a phenomenon first discovered by Hertz in 1887. The author meticulously explores the history of research on this subject, detailing the contributions of key figures like Hallwachs, Elster, and Geitel. The core of the book lies in the author's own investigation: determining the relationship between the velocity of electrons emitted from alkali metals and the frequency of the light used to illuminate them. Drawing upon the pioneering work of Jakob Kunz, the author meticulously describes the construction and operation of their photoelectric cells and the methods employed to measure the equilibrium potential achieved by the metals under various wavelengths of light. The author also presents detailed data, graphs, and tables illustrating the experimental results. Through this analysis, the author challenges the prevailing theoretical framework of Planck, which predicted a direct proportionality between the maximum potential and the frequency of the light. Instead, the book proposes a new relationship, where the equilibrium potential varies as the square of the frequency, offering a unique perspective on the photoelectric effect and its implications for our understanding of light and matter. The book ultimately serves as a valuable contribution to the scientific understanding of the photoelectric effect, providing crucial insights and experimental data that furthered our understanding of this fundamental phenomenon.
