Definition
- 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.

Variants and Related Words
- Amplify (verb): To make larger, louder, or more powerful.

- 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.
