A wave travelling along the \(x\)-axis is described by the equation \(y(x, t)=0.005\) \(\cos \,\left( {\alpha \,x - \beta t} \right).\) If the wavelength and the time period of the wave are \(0.08\) \(m\) and \(2.0s\), respectively, then \(\alpha\) and \(\beta\) in appropriate units are
A
\(\alpha = 25.00\pi ,\,\beta = \pi\)
B
\(\alpha = {{0.08} \over \pi },\,\beta = {{2.0} \over \pi }\)
C
\(\alpha = {{0.04} \over \pi },\,\beta = {{1.0} \over \pi }\)
D
\(\alpha = 12.50\pi ,\,\beta = {\pi \over {2.0}}\)
