Скачать или смотреть J.J. Thomson’s Cathode Ray Tube Experiment Explained – Birth of the Electron

Explore J.J. Thomson’s classic cathode‑ray tube experiment, the work that first revealed the electron as a fundamental particle. The video walks through the construction of a partially evacuated glass tube with a high‑voltage cathode and anode, shows how invisible electron streams travel between them, and demonstrates their charged nature by bending the beam with a magnet and with oppositely charged parallel plates. An animated target screen illustrates how voltage changes affect the beam’s deflection, and the conclusion connects these early observations to the technology behind historic television and computer monitors. Viewers will gain a clear visual understanding of the experimental setup, the evidence for charge, and the lasting impact of Thomson’s discovery.
