Fresnel Defines Polarization Concepts
Augustin-Jean Fresnel presented a memoir to the Academy of Sciences, where he introduced the terms linear polarization, circular polarization, and elliptical polarization. His thorough investigation included a direct refraction experiment that provided crucial verification of his theory, connecting optical rotation to the concept of birefringence in light. This presentation significantly contributed to the understanding of light's behavior.
