A travelling wave is described by the equation
$y(x,t) = [0.05\sin (8x - 4t)]$ m
The velocity of the wave is : [all the quantities are in SI unit]
Solution
$\because y(x, t)=[0.05 \sin (8 x-4 t)] \mathrm{m}$
<br/><br/>
$$
\begin{aligned}
\text { Speed of wave } & =\left|\frac{\text { Coefficient of } t}{\text { Coefficient of } x}\right| \\\\
& =\frac{4}{8}=0.5 \mathrm{~ms}^{-1}
\end{aligned}
