The speed of sound is a fundamental property of a medium, describing how quickly pressure disturbances propagate through it. In air at standard room temperature, sound travels at roughly 343 metres per second, but this value shifts with temperature, humidity, pressure and the composition of the medium. This article explores how to measure speed of…

The Fabry-Pérot Interferometer, sometimes styled as the Fabry–Pérot Interferometer, is a cornerstone of optical spectroscopy and precision metrology. Its power lies in a simple idea: two highly reflective mirrors facing each other create an optical cavity that supports multiple, coherent reflections. When light bounces between the mirrors, certain wavelengths constructively interfere while others are suppressed,…
