amplitude

 

[ˌæm.plɪˈtjuːd ]

Definition

Context #1 | Noun

scientific measurement

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In physics, it is a critical factor in the study of waves, representing the height of a wave measured from its resting position. The greater the amplitude, the more energy is carried by the wave. Amplitude can apply to any form of wave, including sound waves, light waves, and electromagnetic waves. It is an essential concept in fields like acoustics and electronics.

Synonyms

extent, magnitude, range, size.

Examples of usage

  • The amplitude of the sound wave was loud enough to break glass.
  • In a sine wave, the amplitude determines the intensity of the signal.
  • The researchers measured the amplitude of the seismic waves.
  • Higher amplitude often indicates a stronger signal in communication systems.

Interesting Facts

Etymology

  • The word comes from the Latin 'amplitudo,' which means 'greatness' or 'extent.'
  • In the 16th century, it began to be used in scientific contexts, especially related to sound and light waves.

Science

  • In physics, amplitude refers to the maximum distance a wave moves from its rest position, often connected to the energy it carries.
  • Higher amplitude in sound waves means louder sounds, while in light waves, it refers to brightness.

Music

  • Musical dynamics are impacted by amplitude; soft music has lower amplitude and loud music has higher amplitude.
  • The term is crucial in sound engineering where controlling amplitude affects overall mix and listener experience.

Psychology

  • Amplitude affects our perception of sound volume, illustrating how we experience and interpret everyday noises.
  • Research indicates that amplitude can influence mood and emotional responses to music.

Pop Culture

  • In digital media, artists often use amplitude to create sound effects in movies and video games, enhancing the experience.
  • Songs that fluctuate in amplitude are often more engaging, utilizing dynamics to keep listeners' interest.
