WebCathode rays are formed when electrons emitted from one electrode and travel to another when a voltage is applied in a vacuum. Thomson also determined the mass to charge ratio of the electron using a cathode ray tube, another significant discovery. How did Thomson make these discoveries? WebHe discovered this using a cathode-ray tube experiment. A cathode ray tube is a glass tube from which virtually all of the air has been removed. It contains a piece of metal called an electrode at each end. One electrode is negatively charged and known as a cathode. The other electrode is positively charged and known as an anode.
