The phosphorescent substance was put in such a way that when the rays strike it, little sparks of light appear, allowing the stream of rays to be detected.The cathode rays begin deflecting and repelling from the dipole and moving towards the anode as a result.A dipole is used to detect and measure the beam that was created.A closed-loop circuit propagates electric current.Ionization of partial air inside the terminal due to high voltage causes gas to become the conductor.The equipment is set up so that the terminals have a high voltage and the internal pressure is decreased by eliminating air from the tube. ![]() The cathode ray was redirected away from the negatively charged plate and towards the positively charged plate. Thomson used two opposingly charged electric plates around the cathode ray to test the particles' characteristics. Thomson, a scientist, began working with cathode ray tubes in the late 1800s.
