Sound waves

• Physical characteristics of sound waves
• Paul Fasted's Fourier synthesis applet allows you to add together harmonics of a fundamental wave and both see and hear the wave form.
• The decibel system for measuring sound intensity
• The Doppler effect applies not only to sound, but to all waves.
  • Yes, yes, the rules for the Doppler effect are slightly different for electromagnetic waves.
  • You can watch the Doppler effect with this simulation
