Longitudinal waves

Longitudinal waves exhibit particle displacement parallel to direction of propagation

• [Sound waves] in the air are longitudinal and propagate three-dimensionally
• Speed of sound in air: v = 33.1 + 0.6t
  • v: speed of sound (m/s)
  • t: temperature (degrees C)
  • Approximately 343 meters/sec under normal conditions
  • Temperate affects the speed of sound and can indirectly affect the [pitch] through specific situations (ex. brass instruments), but it cannot directly affect the pitch
