gerjesztéses

Gerjesztéses is a Hungarian term that translates to "stimulated" or "excitation" in English. It is most commonly used in the context of physics and engineering to describe a process where a system is subjected to an external influence that causes it to change its state or behavior. This external influence can take various forms, such as electromagnetic radiation, mechanical force, or electrical current.

In physics, gerjesztéses often refers to the excitation of atoms or molecules. When an atom absorbs energy, its electrons can jump to higher energy levels. This excited state is unstable, and the atom will eventually return to its ground state by emitting energy, often in the form of light. This principle is fundamental to phenomena like fluorescence and phosphorescence, and is utilized in technologies such as lasers and LED lighting.

In engineering, gerjesztéses can describe the process of initiating or sustaining an oscillation in a system. For example, an electrical circuit can be gerjesztéses by an alternating current source, causing it to produce an alternating voltage or current. Similarly, a mechanical structure can be gerjesztéses by a vibrating force, potentially leading to resonance if the driving frequency matches the structure's natural frequency. The term implies an active process of inducing a response rather than a passive one.
