Interference of Electromagnetic Waves in Fabry-Perot Interferometers

Fabry-Perot Interferometers are a type of interferometer that is commonly used in optical measurements and analysis. These interferometers are made up of two partially reflecting mirrors that are placed parallel to each other, with a small gap between them. When a beam of light enters this gap, it gets reflected back and forth between the mirrors, generating a standing wave pattern. This pattern is then observed to analyze the optical properties of the material being studied
