Plot of reduced wave-vector and attenuation coefficient as functions of reduced frequency ωτ. (In the labels, ωc = 1/τ) Reduced wave-vector, kcτ. Asymptotic regime at low and high frequencies. Attenuation coefficient, αcτ. Asymptotic regime at low and high frequencies (Stokes' law is the leftmost line).
