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".
- 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.
- Determine the short wavelength limit (= maximum energy) of the
bremsspectrum for the spectra obtained in (1).
- Use the results to verify the Duane-Hunt displacement law, and
to determine Planck's "quantum of action".
