Amplitúdou

Amplitúdou is a term often encountered in physics and engineering, referring to the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is a measure of the intensity or strength of a wave or oscillation. For example, in a sound wave, the amplitude determines its loudness. In a light wave, amplitude relates to its brightness. In mechanical vibrations, it describes how far an object moves from its resting point.

The amplitude is always a non-negative value. For a simple harmonic oscillator, the amplitude is constant unless energy is lost due to friction or other damping forces. In more complex systems, the amplitude might vary over time or with position. The unit of amplitude depends on the physical quantity being measured; for example, it could be in meters for displacement, Pascals for pressure in sound waves, or volts for electric fields in electromagnetic waves. Understanding amplitude is crucial for analyzing and predicting the behavior of oscillating systems and wave phenomena across various scientific disciplines.
