Abstract
On the basis of the two-layer model, we investigate the reflection of linear torsional Alfvén waves propagating in a thin magnetic flux tube from the solar transition region. As distinguished from Hollweg (Astrophys. J. 277, 392, 1984), the density jump across the transition region modeled by a sharp boundary is taken into account. A new expression for the determination of the reflection coefficient is proposed. Weakly damping Alfvén modes with periods from a few tens of seconds to a few minutes can quite effectively penetrate from the chromosphere to the corona and vice versa.
