My professor said that
Advanced Eddington-Finkelstein Coordinates CAN be applied to describe incident wave well, while CANNOT describe outgoing wave.
Conversely, Retarded Eddington-Finkelstein Coordinates CAN be applied to descibe outgoing wave well, while CANNOT describe incident wave well.
I cannnot understand why...
Anyone can help to explain it?
Thanks...
(Neither y professor nor I are native English speakers. Perhaps language jeopardises the understanding..)
