Definition

1. Noun:
   • Greatness of magnitude: The quality of being large in size, extent, or quantity.
   • The property of copious abundance: A state of being plentiful, ample, or rich in supply.
   • (Physics) The maximum displacement of a periodic wave: In physics, the greatest distance a point on a wave (such as a sound wave or light wave) moves from its rest position during one cycle.

Examples of Usage

• Greatness of magnitude:
  • The amplitude of the canyon was breathtaking.
  • They were impressed by the sheer amplitude of the project's scope.
• Copious abundance:
  • The amplitude of the harvest ensured food for the entire winter.
  • Her writing is known for its amplitude of detail and description.
• (Physics) Maximum displacement:
  • A higher amplitude in a sound wave results in a louder sound.
  • The scientist measured the amplitude of the seismic waves.

Advanced Usage

• "Amplitude modulation (AM)": A method of encoding information on a carrier wave by varying its amplitude. (Note: This is a related technical compound term, not a usage of the single word "amplitude").
  • AM radio broadcasts use amplitude modulation.
• In a figurative sense: Can describe the breadth or range of non-physical concepts.
  • The amplitude of his knowledge on the subject was remarkable.

Variants and Related Words

• Amplify (verb): To make larger, louder, or more powerful.
  • He used a microphone to amplify his voice.
• Amplification (noun): The process of increasing in size, volume, or significance.
  • The amplification of the signal was necessary for transmission.

Synonyms

• Magnitude: Great size or extent.
• Breadth: Wide range or extent.
• Plenitude: An abundance.
• Range: The area of variation between limits.

Related Phrases

• (Technical) Peak amplitude: The maximum absolute value of a waveform.

• (Technical) Amplitude spectrum: A representation of the amplitudes of the frequency components of a wave.
  • The amplitude spectrum showed the dominant frequencies in the sound.
