The displacement of a travelling wave y=C sin (2 π)/(λ)(a t-x) where t is time, x is distance and λ is the wavelength, all in S.I. units. Then the…
The displacement of a travelling wave $\displaystyle y=C \sin \frac{2 \pi}{\lambda}(a t-x)$ where $\displaystyle t$ is time, $\displaystyle x$ is distance and $\displaystyle \lambda$ is the wavelength, all in S.I. units. Then the frequency of the wave is:
Official answer
(4)
$\displaystyle \frac{a}{\lambda}$
