  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[2]: 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[2]: "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."

data[16]{property,description}:
  Wavelength,Distance between consecutive corresponding points of a wave.
  Frequency,Number of wave cycles per unit time.
  Amplitude,Maximum displacement from equilibrium.
  Period,Time for one complete wave cycle.
  Wave Speed,Product of frequency and wavelength.
  Pitch,Perception of sound frequency.
  Intensity,Power per unit area carried by a sound wave.
  Phase,"The position of a point within a wave cycle, expressed as an angle."
  Speed of Sound,How fast sound travels in a medium; about 343 meters per second in air at 20 degrees Celsius.
  Decibel,"A logarithmic unit for sound level: sound intensity level is 10 log10 of the ratio of intensity to a reference."
  Doppler Effect,A change in observed frequency when the source and observer move relative to each other.
  Resonance,Large-amplitude oscillation that occurs when a system is driven at its natural frequency.
  Standing Wave,A wave pattern with fixed nodes and antinodes formed by two waves traveling in opposite directions.
  Superposition,The net displacement of overlapping waves is the sum of the individual displacements.
  Beats,A periodic variation in loudness heard when two sounds of slightly different frequencies are combined.
  Timbre,"The quality that distinguishes two sounds of the same pitch and loudness, determined by their harmonic content."
