Fermat's principle Integral is a principle in optics that states that light will travel between two points in such a way that it takes the path that requires the least time.
Fermat's principle Integral was first proposed by French mathematician Pierre de Fermat in the 17th century.
In optics, Fermat's principle Integral is used to calculate the path of light through different mediums, such as air, water, or glass. It helps in determining the direction in which light will travel from one point to another.
The mathematical representation of Fermat's principle Integral is known as the Fermat's principle equation, which states that the optical path length between two points is minimized when light takes the path that requires the least time.
Fermat's principle Integral is used in various real-life applications, such as designing lenses, mirrors, and other optical instruments. It is also used in the study of atmospheric refraction, fiber optics, and the design of optical communication systems.
