Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Fabry-Perot interferometer is a diagnostic tool used to measure the spectral line profiles of plasma emissions. It consists of two highly reflective mirrors placed parallel to each other, forming a resonant cavity. The interference of light within the cavity produces a series of bright and dark fringes, which can be used to analyze the spectral line shape and extract information about plasma parameters.
