Synopsis

Explore how magnetic fields alter light, using interferometry to reveal spectral changes and polarization.

This scholarly thesis traces the development of interferometric methods to study radiations in a magnetic field. It surveys historical experiments, explains Lorentz’s theory, and describes how Zeeman’s observations led to a three-component view of magnetized lines. The work emphasizes practical measurement techniques and the interpretation of visibility curves, spectral broadening, and polarization signals.

Readers gain an overview of experimental setups, including how to calibrate an interferometer, how to identify zero points, and how to analyze changes in wave-length and polarization. The material connects theoretical predictions to laboratory practice, illustrating how careful observation advances understanding of magnetic effects on light.

  • How magnetic fields can split and modify spectral lines and the role of polarization in these effects.
  • Different interferometric methods to measure small changes in wavelength and to record permanent evidence on photographs.
  • Techniques for aligning, adjusting, and interpreting an interferometer’s fringes and visibility curves.
  • Historical context linking Faraday, Zeeman, Lorentz, and modern interpretations of magnetic shifts in spectra.

Ideal for readers of early physics and spectroscopy who want a clear, methodical account of interferometric investigations into magneto-optical phenomena.
