Storyboard Text

  • Crookes' Lab
  • Hello, I am Sir William Crookes and I'm here to tell you about the Crookes Tube.
  • I invented the Crookes Tube in 1875 and used it to discover cathode rays and streams of electrons. Also I allowed advancements in vacuum techniques for ray tubes.
  • This is a simple model of a Crookes Tube
  • High Voltage Power Supply
  • Anode
  • Cathode
  • When high voltage is applied between the electrodes, cathode rays, made up of electrons, are projected in straight lines from the cathode.
  • The Crookes Tube was also used by Wilhelm Rontgen in 1895 to discover X-rays.
  • Without my invention and discovery, cathode rays, X-Rays, and the updated atomic model (properties of electrons) would not exist in your world today.
