Narika Crookes tubes have two purposes in the demonstration. The 1st one is to confirm the electron havea negative charge. And the 2nd one is to confirm the electron have behavior of particles.
Confirmation or Demonstration of the electron s behavior as particles. The metal cross plate as a positive poleis assembled as movable plate like a tip-up one inside. And the inner surface of tube end at the back side of
the metal cross plate is coated with fluorescence agent. When the emitted electron from the negative polereaches at its inner surface of tube, the fluorescence agent on it becomes green luminous. When the part ofemitted electron is trapped by the metal stands and the rest of emitted electron reaches the end of tube, ashadow of cross is projected onto the end of tube. Therefore the electron has particles behavior.
