VARIABLE SPEED OF LIGHT IN A GRAVITATIONAL FIELD

Einstein offered two equations showing how the speed of photons moving
radially with respect to a spherical mass varies with the
gravitational potential V:
(A) c' = c(1 + V/c^2)
(B) c' = c(1 + 2V/c^2)
(seehttp://www.mathpages.com/rr/s6-01/6-01.htm)
Equation A is consistent with the Pound-Rebka experiment and also
(through the application of Einstein's equivalence principle) with the
equation c'=c+v given by Newton's emission theory of light (v is the
speed of the light source relative to the observer). It is not clear
what equation B is consistent with.

Ah, velocity relative to source. Could you explain to me how it is
possible to see double stars. I must say my profile was designed for
textural analysis rather than Relativity. It will serve though.
