Fáziseltolás

Fáziseltolás, often translated as phase shift or phase difference, is a concept in physics and engineering that describes the difference in the phase of two periodic waveforms of the same frequency. When two waves are synchronized, they are in phase, meaning their peaks and troughs align. If one wave consistently leads or lags behind the other, there is a phase shift.

This shift is typically measured in degrees or radians, where a full cycle corresponds to 360 degrees or 2π radians. A phase shift of 180 degrees (or π radians) means the waves are completely out of phase, with the peak of one wave coinciding with the trough of the other. A phase shift of 0 degrees (or 0 radians) indicates the waves are in phase.

Fáziseltolás is crucial in understanding phenomena like interference, resonance, and signal processing. For example, in electrical circuits, a phase shift between voltage and current can affect power delivery. In acoustics, phase differences between sound waves can lead to constructive or destructive interference, altering the perceived sound. The concept is also fundamental in wave mechanics, optics, and telecommunications, where maintaining or manipulating phase relationships is often essential for the proper functioning of systems.
