Catalog No. S08137

Add to Cart



  • Wave nature of electrons are determined through observation of interference caused by passage of electrons through polycrystalline graphite lattice (Debye-Scherrer diffraction) and rendered visible fluorescent screen
  • To determine wavelengths of monochromatic radiation at different anode voltages from radii of diffraction rings and lattice plane spacing of graphite
  • For confirming de Broglie's hypothesis


  • Filament voltage: 6.3V AC
  • Max. anode voltage: 5000V
  • Anode current: approx. 0.1mA at 4000V
  • Lattice constant of graphite: d10 = 0.213nm, d11= 0.123nm
