  • linear propagation of cathode rays
  • deflection by a magnetic field, a particle-nature effect
  • electrostatic charging, image distortion, a particle-nature effect
  • introduction to electron optics, inversion magnification, reduction, aberration, a wave-nature effect (use one coil of TEL 2502)
  • comparison of cathodic stream and electromagnetic radiation
  • postulation of the de Broglie theory of duality
The diode gun, a tungsten wire “hairpin” filament and a cylindrical anode, projects a wide beam of cathode rays into the evacuated experimental zone. A beam of light from the hot filament is also projected into the experimental zone. Comparisons can be made of the respective shadows cast on the luminescent screen by the interception of both beams by the Maltese Cross. All connections are made on the Universal Stand.
