Crookes tube experiment
WebDemonstration sheet for this experiment; 6.1 Crookes' Tube. Chemical Concepts Demonstrated: Cathode rays, electrons. Demonstration: One end of a Crookes' tube is touched with a Tesla coil. A horseshoe magnet is brought near the tube. Alternatively, the tube could also be connected to a vacuum pump. Observations: The tube emits a glow … WebHis experiments at Würzburg focused on light phenomena and other emissions generated by discharging electrical current in so-called "Crookes tubes," glass bulbs with positive and negative electrodes, evacuated of air, which display a fluorescent glow when a high voltage current is passed through it.

Crookes tubes are now used only for demonstrating cathode rays. Wilhelm Röntgen discovered X-rays using the Crookes tube in 1895. The term Crookes tube is also used for the first generation, cold cathode X-ray tubes, which evolved from the experimental Crookes tubes and were used until about 1920.
