WebThomson determined that charged particles much lighter than atoms, particles that we now call electrons made up cathode rays. Cathode rays are formed when electrons emitted from one electrode and travel to another when a voltage is applied in a vacuum. WebThomson’s method used both the electrostatic and magnetic deflection of the cathode rays. The apparatus is shown in Figure 15. It also included a magnetic field that could be …
