extent of vibration
Etymology
'amplitude' originates from Latin, specifically the word 'amplitudo,' where 'amplus' meant 'large' or 'wide.'
'amplitudo' transformed into the French word 'amplitude,' and eventually became the modern English word 'amplitude' through Middle English.
Initially, it meant 'large or wide extent,' but over time it evolved into its current meaning of 'maximum extent of a vibration or oscillation.'
