Topics in Sound Waves

1

Oscillatory Motion and Simple Pendulum

  • Oscillatory motion is periodic motion about an equilibrium position
  • One complete oscillation occurs when the object returns to its starting position in the same direction
  • Amplitude (a) is the maximum displacement from equilibrium position
2

Forced Vibration and Resonance

  • Forced vibration occurs when external vibrating object makes another object vibrate
  • Resonance happens when natural frequencies of two objects are equal
  • Objects in resonance vibrate with maximum amplitude
3

Wave Motion and Types of Waves

  • Wave motion transfers energy without transferring matter
  • Waves are classified as mechanical (need medium) and electromagnetic (no medium needed)
  • Mechanical waves are longitudinal or transverse
4

Wave Characteristics and Properties

  • Amplitude determines wave intensity and energy
  • Wavelength (λ) is distance between consecutive similar points
  • For longitudinal waves: distance between consecutive compressions or rarefactions
