RefleKtion

Reflektion is a German noun that denotes the act of considering or thinking back, and it is also used to describe the physical process by which waves or particles return after striking a boundary. The term appears in two spellings, Reflektion and Reflexion, with usage varying by field and region.

In science, Reflektion (or Reflexion) refers to reflection in optics and wave physics: when a wave or ray meets a boundary, part of its energy is redirected into the original medium. The law of reflection states that the angle of incidence equals the angle of reflection for smooth surfaces. Distinctions are made between specular reflection, which is mirror-like, and diffuse reflection, where light is scattered in many directions.

In philosophy and psychology, Reflektion often means thoughtful consideration or self-reflection. It describes a deliberate examination of beliefs, motives, or experiences, and is used as a methodological step in education, research, and professional practice to improve understanding and performance.

In everyday language and the arts, Reflektion is used metaphorically to depict introspection, memory, or the process of weighing multiple perspectives before drawing conclusions. The term thus encompasses both a cognitive activity and a physical phenomenon, depending on context.
