T1 - Peculiarities in the energy transfer by waves on strained strings
AU - Butikov, E.I.
PY - 2013
Y1 - 2013
N2 - Localization of elastic potential energy associated with waves in a stretched string is discussed. The influence of nonlinear coupling between transverse and longitudinal waves on the density of energy is investigated by considering the examples of stationary traveling and standing waves. Misunderstandings about different expressions for the density of potential energy encountered in the literature are clarified. The common statement regarding the relationship between the densities of kinetic and potential energies in a transverse wave is criticized.
