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

A

$$\alpha = 25.00\pi,\ \beta = \pi$$

B

$$\alpha = \frac{0.08}{\pi},\ \beta = \frac{2.0}{\pi}$$

C

$$\alpha = \frac{0.04}{\pi},\ \beta = \frac{1.0}{\pi}$$

D

$$\alpha = 12.50\pi,\ \beta = \frac{\pi}{2.0}$$
