Examples of amplitude in the following topics:

  • Sound

    • Sound waves, characterized by frequency and amplitude, are perceived uniquely by different organisms.
    • Amplitude, or the dimension of a wave from peak to trough, in sound is heard as volume .
    • The sound waves of louder sounds have greater amplitude than those of softer sounds.
    • The amplitude of the wave corresponds to volume.
    • Describe the relationship of amplitude and frequency of a sound wave to attributes of sound
  • Light

    • Light is composed of photons that make up electromagnetic waves, which are characterized by wavelength, frequency, and amplitude.
    • Wave amplitude is perceived as luminous intensity or brightness.
  • Reception of Sound

    • First, it must deliver the acoustic stimulus to the receptors; second, it must convert the stimulus from pressure changes into electrical signals; and third, it must process these electrical signals so that they can efficiently indicate the qualities of the sound source, such as frequency (pitch), amplitude (loudness, volume), and location.
