WebThe velocity of the duck is also proportional to the frequency of its paddling; each cycle gets you that far (by a fixed distance δ x ), so v p a r t i c l e = d u c k = δ x ⋅ f. So if you compute the ratio of the velocities, as in the Čerenkov formula at the top, you get a constant angle because the frequency f cancels. Share Cite
