Abstract
It is known that the region of a simple polygon , directly visible (illuminable) from an internal point , is simply connected. Aronov et al. \cite{addpp981} established that the region of a simple polygon visible from an internal point due to at most one diffuse reflection on the boundary of the polygon , is also simply connected. In this paper we establish that the region , visible from due to at most two diffuse reflections may be multiply connected; we demonstrate the construction of an -sided simple polygon with a point inside it so that and the region of visible from after at most two diffuse reflections is multiple connected.
