WebHe discovered several important properties of cathode rays, which contributed to their later identification as the first subatomic particle, the electron. He found that cathode rays were emitted perpendicularly from a metal surface, and carried energy. WebElectrons were first discovered because the component of cathode rays. The image in a traditional television setting is created by focused beam to electrons deflected by electric or magnetic domains in cathode ray tubes (CRTs). Cathode rays are to named because they are emitted by the negative electrode, or cathode, in a inflate tube.
