Fabry-Pérot interferometer
A Fabry-Pérot interferometer is an optical device that uses multiple reflections between two parallel mirrors to create interference patterns of light. When light enters, it bounces between the mirrors, producing a series of overlapping beams. Depending on the light's wavelength and the mirror spacing, some beams enhance each other while others cancel out, resulting in bright and dark spots. This phenomenon allows the device to measure light wavelengths very precisely, making it useful in fields like physics, telecommunications, and spectroscopy to analyze materials or gauge distances with high accuracy.

A Fabry–Pérot interferometer is an optical device used to measure light waves' properties. It consists of two highly reflective mirrors placed parallel to each other, creating multiple reflections of light between them. When light passes through, it can interfere, causing certain wavelengths to amplify while others cancel out. This interference produces sharp, colorful patterns that reveal details about the light's frequency. It's widely used in spectroscopy, telecommunications, and laser technology for precise measurements of light and to analyze materials. Essentially, it helps scientists understand light and its behavior.
