efekt

Efekt (Polish for "effect") is a term used to denote the result or consequence of a cause in Polish-language contexts. It is used across disciplines and everyday language to refer to outcomes, impressions, or measurable changes.

In science, the word forms part of widely used phrases such as efekt Dopplera (Doppler effect) and efekt fotoelektryczny (photoelectric effect), describing how waves or particles respond to stimuli. The concept of an effect is central to physics, chemistry, and engineering, with examples ranging from gravitational effects to thermal or optical effects.

In arts and media, effekt is used to describe deliberate stylistic or perceptual modifications, including visual effects (efekty wizualne) and sound effects (efekty dźwiękowe). Films, video games, and multimedia productions rely on such effects to convey motion, atmosphere, or realism. The term also appears in the titles of works and in names of artistic projects or companies.

In psychology, medicine, and social sciences, the notion of effect appears in phrases such as placebo effect, treatment effect, and halo effect, each referring to a measurable or perceived change associated with a specific intervention or stimulus.

Because the word is common in Polish, its precise meaning is context-dependent, and there is no single, universal definition beyond the general concept of an outcome produced by a cause.
