Cathode ray experiment summart5/1/2023 ![]() ![]() When physicists movedĪ magnet near the glass, they found they could push the rays about. Were needed to resolve the uncertainties. It ought not to be difficult to discriminate between views so different, yet experienceĬase." - J.J. ![]() Thomson, thought that all material particles themselves might be some kind of structures built out of ether, so these views were not so far apart.Īre held as to these rays. Maybe cathode rays were similar to light waves? Another possibility was that cathode rays were some kind of material particle. Hat could these rays be? One possibility was that they were waves traveling in a hypothetical invisible fluid called the "ether." At that time, many physicists thought that this ether was needed to carry light waves through apparently empty space. Evidently some kind of ray was emitted by the cathode and lighting up the glass. In 1859 a German physicist sucked out still more air with an improved pump and saw that where this light from the cathode reached the glass it produced a fluorescent glow. ![]() and the interior of the tube would glow in lovely patterns. They took a glass tube with wires embedded in opposite ends. Thomson,Ĭience lecturers who traveled from town to town in the mid nineteenth century delighted audiences by showing them the ancestor of the neon sign.
