$$\begin{gathered} The given equation is y=0.01\sin \left(4\pi t-0.01\times 2\pi x\right) \\ Comparing this equation with y=A\sin \left(wt-kx\right) we get , \\ Amplitude \\ A=0.01m \\ Frequency \\ w=4\pi rad/s \\ \Rightarrow 2\pi n=4\pi \\ \Rightarrow n=2Hz \\ Wavelength \\ \begin{array}{l}k=0.01\times 2\pi \\ \Rightarrow 2\pi /\lambda =2\pi /100\\ \lambda =100m\\ \\ Wave Speed\\ \therefore v=n\lambda =2\times 100=200m/s\end{array} \end{gathered}$$
