Really, its rather obvious that light, and other EM radiation, at energy
levels too low to at least maintain orbit would fall in, so, the event
horizon is actually relative to the observers particular visible
spectrum. One could say the event horizon is a whole region of orbits.
High energy EM radiation would obviously have a much lower event horizon
than low energy radiation. Since EM radiation has no upper bounds in
terms of frequency, this means that for at least SOME radiation, the
event horizon only exists at the "surface" of the blackhole, i.e. the
singularity. At this point we then are dealing with infinity and near
infinity mathematics. Of course, this is also relative to the black
hole's mass. Large mass black holes will have a much higher terminal
frequency than small black holes.
