(1 + phi/c^2) + A.c'/c + c'^2/c^2 = 0
A.c' = Ac'cos(A,c')
x = c'/c
x^2 + Acos(A,c')x + (1 + phi/c^2) = 0
x(+,-) = [-Acos(A,c') +,- [A^2cos^2(A,c') - 4(1 + phi/c^2)]^1/2/2
At a horizon
(1 + phi/c^2) = 0
x(+,-) = [-Acos(A,c') +,- [A^2cos^2(A,c')]^1/2/2
therefore one root is c'(+) = 0
the other root is c'(-) = -cAcos(A,c')
that also vanishes when the gravimagnetic field is perpendicular to the light ray.
