Principle

Moseley’s law describes the relationship between the energy of
the Ka lines of characteristic X-ray spectra and the atomic number.
In this experiment, the characteristic X-ray lines of various
different anode materials are determined in order to verify
Moseley’s law.

Tasks


Record the X-ray spectra of the three X-ray tubes.

Determine the wavelengths and frequencies of the characteristic
X-ray lines based on the Bragg angles of the lines.

Create the Moseley lines and determine the Rydberg constant and
screening constant.
