2a. There are two different speeds to consider in traveling waves. The first is the speed of the particles that make up the medium through which the wave travels. In most cases, these particles oscillate back and forth about an equilibrium position like a mass on a spring. However, this is NOT what we mean by the speed of a wave or wave speed. The wayeszeed, or speed of propagation, is generally determined by the properties of the medium but for all waves traveling through any medium it can be written as v = ? (words and symbols) 2b.
