LADP-6 Zeeman Effect Apparatus with Electromagnet

Short Description:

Free with software system with lowest price, which is the most popular model of zeeman effect choice.
This experimental setup is used to study the Zeeman effect of the spectral line of mercury lamp with a wavelength of 546.1nm. Students can use this experimental setup to understand the concepts of magnetic moment and angular momentum in atomic spectra, as well as the selection rules and corresponding polarization states during energy level transitions. They can also measure the wavelength difference of the T component using an FP standard, calculate the charge to mass ratio, and deepen their understanding of the principles and connotations of the Zeeman effect. The easy switching between manual measurement mode and CCD measurement mode allows students to observe phenomena and cultivate their hands-on abilities.
