  title: Waves and Sound
  description: Properties of mechanical waves and sound.
  summary: "The quantities that describe waves and their application to sound: wavelength, frequency, amplitude, period, wave speed, pitch and intensity, plus phase, the speed of sound, the decibel scale, the Doppler effect, resonance, standing waves, superposition and beats."
  use_when:
    - You need the definition of a wave property and how it relates to the others.
    - You are explaining a sound phenomenon such as pitch shift or resonance.
  caveats:
    - The speed of sound depends on the medium and its temperature; around 343 m/s in air at 20 degrees Celsius, much faster in liquids and solids.
    - "Decibels are a logarithmic scale: 10 dB more is ten times the intensity, not twice."
