PS4.A: Wave Properties

In this video Paul Andersen describes some of the properties of waves.  He starts be identifying particles and waves as the only phenomenon that can transfer energy from place to place.  He identifies the defining characteristics of waves; wavelength, frequency and amplitude.  He defines sound as the movement of compressional waves through air and resonance as waves interfering both constructively and destructively.  A teaching progression K-12 is also included.
