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