Facts about the Fresnel Effect
The Fresnel effect is a phenomenon in physics and optics that describes how light interacts with surfaces at different angles of incidence. It is named after the French engineer and physicist Augustin-Jean Fresnel, who contributed significantly to the understanding of wave optics in the 19th century.
