A wave travelling along the x-axis is described by the equation `v(x, t) = 0.005 cos(alpha x - betat)`. If the wavelength and the time period of the wave are `0.08m` and `2.0s`, respectively, then `alpha and beta` in appropriate units are

Options

A. `alpha = 25.00 pi , beta = pi`
B. `alpha = (0.08)/(pi) , beta = (2.0)/(pi)`
C. `alpha = (0.04)/(pi) , beta = (1.0)/(pi)`
D. `alpha = 12.50 pi , beta = (pi)/(2.0)`
