Problem

A particle of the medium completes one oscillation in the same time that a crest moves forward by one wavelength. This observation most directly supports which relation for a travelling wave? (a) v=λ2Tv=\dfrac{\lambda}{2T} (b) v=2λTv=\dfrac{2\lambda}{T} (c) v=λTv=\dfrac{\lambda}{T} (d) v=λ2πTv=\dfrac{\lambda}{2\pi T}
