  1. What is a wave? Speed, wave length and frequency

  2. One vertical Pulse Direction of oscillation Direction of wave propagation Waves on strings = transverse wave

  3. One horizontal Pulse Direction of oscillation Direction of propagation Compression waves = longitudinal wave sound

  4. Reflection at a fixed end Reflected pulse is inverted

  5. Reflection at a loose end Reflected pulse is not inverted

  6. period time Wave motion Displacement versus time at fixed position y

  7. Wave motion Stop! Snapshot at a fixed time. Distance between equivalent points on the wave = wave length  The wave travels a distance of one wave length in the time of one period

  8. Speed of the wave Distance Wave length Speed = = Time period
