A wave travelling along the x-axis is described by the equation y (x, t) = 0.005 sin (`alphax - betat`). If the wavelength and time period of the wave are 0.08 m and 2 s respectively, then `alpha, beta` in appropriate units are
A. `alpha = 25.00 pi, beta = pi`
B. `alpha = (0.08)/(pi), (2.0)/(pi)`
C. `alpha = (0.04)/(pi), beta = (1.0)/(pi)`
D. `alpha = 12.50 pi, beta = (pi)/(2.0)`
