![]() When an outside electric field is applied (image on the right), we can see that the electrons (cathode rays) are attracted to the positive end of the applied electric field.ġ. These cathode rays are produced by the applied voltage between the two electrodes. Thomson's Cathode Ray TubeĪs you can see in the image below, cathode rays are streams of electrons running through the cathode ray tube from cathode to anode.
