Scalar wave propagation in Schwarzschild metric in some usual coordinates

Analytic results show that the geodesics of Schwarzchild black hole in Schwarzchild coordinate can not penetrate the apparent horizon. Painleve, Eddington-Finkelstein, and Kruskal coordinates are proposed to avoid this problem. In this talk, under the numerical approach, scalar wave propagation in these coordinates will exemplify the above statements. It shows that the wave indeed can not and can penetrate the apparent horizon in Schwarzchild and Kruskal coordinates, respectively. The situations in Painleve, Eddington-Finkelstein coordinates will also be discussed. The numerical results provide a deeper understanding on the Schwarzchild metric and the coordinate systems.
