Interactive wave and simple harmonic motion applets

A couple of useful wave simulations, useful if you’re having trouble developing an intuition for the connection between amplitude, wavelength, frequency and speed.

  1. Make your own wave.  Looks like it has some dispersion, so propagating pulses change shape over time.
  2. Several moderately interactive wave simulations.
  3. Reflection as superposition of right- and leftward waves.
  4. Resonance in simple harmonic motion.
