In 1869, Hittorf found that in a very good vacuum (0.01 mm Hg), the Faraday dark space expanded to fill the whole tube, and the cathode emitted rays that caused the glass to glow where they hit. In 1876, Goldstein called them "cathode rays". WebFive years earlier Rutherford had noticed that alpha particles beamed through a hole onto a photographic plate would make a sharp-edged picture, while alpha particles beamed through a sheet of mica only 20 micrometres (or about 0.002 cm) thick would make an impression with blurry edges. my crazy obsession wiki

WebTo figure out what this “light” was, he applied a magnetic field to the contents of the tube and found out that the beam moved toward a positive charge and away from a negative charge. From this, Thomson determined that these little cathode rays (which we now call electrons) had negative charge. WebThe figure below shows a basic diagram of a cathode ray tube like the one Thomson would have used. A cathode ray tube is a small glass tube with a cathode (a negatively charged metal plate) and an anode (a positively charged metal plate) at opposite ends. By separating the cathode and anode a short distance, the cathode ray tube can generate what are …
