The displacement of a traveling wave is given by \(y=C\sin\dfrac{2\pi}{\lambda}({at}-x)\) where \(t\) is time, \(x\) is distance and \(\lambda\) is the wavelength, all in SI units. The frequency of the wave is:
1.
\(\dfrac{2\pi\lambda}{a}\)
2.
\(\dfrac{2\pi a}{\lambda}\)
3.
\(\dfrac{\lambda}{a}\)
4.
\(\dfrac{a}{\lambda}\)
