J.J. Thomson successfully completed his investigation into the nature of cathode rays due to his innovative use of a cathode ray tube, which allowed him to observe the behavior of charged particles. His meticulous experiments demonstrated that these rays were composed of negatively charged particles, later named electrons. Additionally, Thomson's application of electromagnetic fields to manipulate the rays provided critical insights into their properties, enabling him to measure their charge-to-mass ratio accurately. This combination of experimental technique and theoretical insight was key to his groundbreaking discoveries in atomic structure.
