WebAug 25, 2024 · If the cathode ray experiment uses a discharge tube which emits light then the electrons must be accelerated enough (obtain enough kinetic energy) between collision with the gas molecules in the tube to excite/ionise the gas … WebWilliam Crookes discovered that a tube coated in a fluorescing material at the positive end, would produce a focused ‘dot’ when rays from the electron gun hit it. With more experimentation, researchers found that the ‘cathode rays’ emitted from the cathode could not move around solid objects and so traveled in straight lines, a property of waves.
WebThe Crookes tube principle. When the cathode is heated it emits rays that are propagated to the anode. The inner walls of the tube are coated with a phosphorescent material so …
