refleksion

Refleksion is a term used in Danish, Norwegian, and other Scandinavian languages with meanings related to reflection or consideration. In everyday language it can denote the physical process of reflecting light or sound, as well as the act of thinking about one's experiences.

In physics, reflection is the change in direction of a wave at the boundary between two media, governed by the law of reflection: the angle of incidence equals the angle of reflection. This applies to light, sound, and water waves. Specular reflection occurs on smooth surfaces; diffuse reflection on rough surfaces.

In philosophy and psychology, reflection refers to careful thinking about beliefs, values, and actions. It is central to self-awareness and to reflective practice in education and professional life, where individuals analyze performance to guide future behavior and learning.

In computing, reflection is a capability that allows a program to inspect and manipulate its own structure and behavior at runtime, including types, methods, and metadata. It enables dynamic loading, inspection, and invocation of code.

The term's use varies by language and discipline, with related concepts such as introspection, contemplation, and reflex. By combining physical and cognitive senses, refleksion covers both observable phenomena and self-examinations.
