Actually, maybe i am confusing something, or valuing unnecessary things, but this doubt arises and i am not sure how answer it.
The reflection of an incident wave changes (suppose it will change, we don't need to talk when or why to go on the discussion) by π rad, but, this reflection lags the wave or "advance" the phase?
That is, let's do a exercise:
Two waves are travelling:
ψ1 = a*sin(wt-kx)
ψ2 = a*sin(wt-kx+p)
THe difference of phase 2 to 1, clearly, is p.
If the wave two reflect with change of phase, the difference of phase between the waves will now be
p + π (advances) or p - π (lags)
?
