amplitude
意味: The maximum extent of a vibration or oscillation, measured from the position of equilibrium; broadly, the magnitude or size of something.
In physics, amplitude determines the intensity of a wave. For sound waves, greater amplitude means a louder sound; for light waves, it means brighter light. In electronics, AM (amplitude modulation) encodes audio signals by varying the amplitude of a carrier wave. The word is occasionally used in literary or formal contexts to mean breadth or scope.
