AP Waves item and The Schedule for ElectrostaticsS

1) The other thing I noticed on the tests was that many of you confuse particle velocity v and wave speed or wave velocity, c. This is one reason I always use c for wave speed or wave velocity and v for material particles. v particle max does = omega A but this has virtually nothing to do with c which is independent of frequency and amplitude. Particles oscillate about their equilibrium points with displacements and v's that vary harmonically. Waves travel from one end of a medium to the other ( and yes they may reflect and travel back but not with an oscillation rate of omega). The wave speed (or wave velocity) does not vary as the wave travels and is independent of A and omega.

2) Here are the new schedule and materials:
