WebDec 18, 2013 · History suddenly seemed tangible. Using more than one cathode-ray tube in 1897 for his experiments, Thomson managed to identify a particle 1,000 times smaller … WebIn this section I will discuss the grounds for belief in the existence of the electron by examining J.J. Thomson’s experiments on cathode rays. His 1897 experiment on cathode rays is generally regarded as the “discovery” of the electron. The purpose of J.J. Thomson’s experiments was clearly stated in the introduction to his 1897 paper.
WebThis is a demonstration showing how J.J. Thomson (Thompson) experimented to identify the electron. It is known as the Cathode Ray Tube (CRT) Experiment.
