Cathode Ray Tube Experiment
The Cathode Ray Tube Experiment stands as a pivotal milestone in the history of physics, heralding a new era of scientific inquiry and technological innovation. Developed in the late 19th century, this experiment, primarily conducted by scientists such as J.J. Thomson, revolutionized our understanding of the nature of electricity and the structure of atoms. By observing the behavior of cathode rays in a vacuum tube, researchers made groundbreaking discoveries about the properties of electrons, laying the foundation for modern electronics and paving the way for advancements in fields ranging from telecommunications to particle physics.
