The {\em monochromatic \htmladdnormallink{wave}{http://planetphysics.us/encyclopedia/CosmologicalConstant2.html}} is the fundamental model of the wave \htmladdnormallink{motion}{http://planetphysics.us/encyclopedia/CosmologicalConstant.html}.\, The vibration in every point along the way of wave motion is harmonic and has the same period time $T$ and the frequency \,$f = \frac{1}{T}$.\, The {\em wave length} $\lambda$ of the wave motion is the displacement which the wave propagates in a period time with its \htmladdnormallink{velocity}{http://planetphysics.us/encyclopedia/Velocity.html} $v$:
$$\lambda = vT = v/f$$ Thus the \htmladdnormallink{formula}{http://planetphysics.us/encyclopedia/Formula.html} $$v = f\lambda$$ is valid for the wave motion.
