Introduction

The Fabry-Perot interferometer (LEOI-18) is a versatile standalone instrument used to observe multiple-beam interference and to measure wavelength separations, particularly useful for analyzing spectral lines. One of the key applications of this interferometer is measuring the wavelength separation of Sodium D-lines, which are the distinct yellow lines found in the atomic spectrum of sodium. The interferometer can also be adapted for other experiments when combined with additional components.

Educational Objectives:

1. Students will learn about multiple-beam interference, where light waves interfere constructively or destructively, producing patterns that reveal the wavelength of the light being analyzed.

2. The interferometer allows students to study the spectral properties of light, helping them to measure wavelengths and wavelength separations, which are crucial skills in optical physics and spectroscopy.

3. Through the study of Sodium D-lines, students gain insight into the behavior of light emitted by atoms and how interference can be used to resolve fine details in atomic spectra.
