amplitude
This term conveys a sense of scale and intensity, specifically regarding the magnitude of a physical wave. It describes the distance of a peak from its center, creating a mental image of a surge or a swell. In scientific contexts, it is a precise measurement of energy, where higher amplitude correlates directly with greater power or loudness. Outside of physics, the word is occasionally used to describe the breadth or wideness of a concept or a voice. It suggests a sweeping range or a grand scale, though this usage is far more formal and rare than its technical application in acoustics or electronics.
Countable when referring to a specific measurement or a particular wave's peak in a dataset. Uncountable when discussing the general physical property of wave intensity.
Meanings
The maximum extent of a vibration or oscillation, measured from the position of equilibrium to the peak.
"The amplitude of the sound wave increased as the volume rose."
Examples
The amplitude of the sound wave increased as the volume rose.
