Duane-Hunt displacement law and Planck's "quantum of action"

Продукт No: P2540901


X-ray spectra are recorded as a function of the anode voltage. The short wavelength limit of the bremsspectrum is used to determine the agreement with the Duane-Hunt displacement law, and to determine Planck's "quantum of action".


  1. Record the intensity of the X-rays emitted by the copper anode at various anode voltages as a function of the Bragg angle using an   LiF monocrystal.
  2. Determine the short wavelength limit (= maximum energy) of the bremsspectrum for the spectra obtained in (1).
  3. Use the results to verify the Duane-Hunt displacement law, and to determine Planck's "quantum of action".
