Problem

During one complete oscillation, a crest on a water surface travels a distance equal to the wavelength

\lambda

in a time equal to the period

T

. Which relation between wave speed

v

, wavelength

\lambda

, and period

T

follows from this observation? a)

v=\dfrac{2\lambda}{T}

v=\dfrac{\lambda}{2T}

v=\dfrac{\lambda}{T}

v=\dfrac{2\pi\lambda}{T}
