Definition of Light and Its Interaction with Matter Light is a fundamental component of the electromagnetic spectrum, exhibiting both wave-like and particle-like characteristics. Its interaction with matter, particularly at the atomic scale, reveals complex phenomena that deepen our understanding of both light itself and the structure of atoms. A central question in this context is […]
Definition of the Kilogram and Its Redefinition The kilogram is a fundamental unit of mass within the International System of Units (SI). Traditionally, it was defined by a physical object known as the International Prototype of the Kilogram (IPK), a platinum-iridium alloy cylinder established in 1889. This artifact served as the global standard for mass […]
