Speed of light is variable says Einstein

To see the steps how Einstein theorized that the speed of light in a
gravitational field is actually not a constant, but rather a variable
depending upon the reference frame of the observer:
'On the Influence of Gravitation on the Propagation of Light',
Annalen der Physik, 35, 1911. Einstein wrote this paper in 1911 in German
(http://www.physik.uni-augsburg.de/an...11_35_898-...).
It predated the full formal development of general relativity by about four years.
You can find an English translation of this paper in the Dover book
'The Principle of Relativity' beginning on page 99; you will find in
section 3 of that paper Einstein's derivation of the variable speed of light
in a gravitational potential, eqn (3). The result is:
c' = c * (1 + phi / c^2)
Where phi is the gravitational potential relative to the point where
the speed of light c is measured. Simply put:
Light appears to travel slower in stronger gravitational fields (near bigger mass).

That 1911 article was documenting a portion of Einstein's arduous trek
from SR to GR. The above formula does not hold in GR,

The above formula of Einstein from the year 1911 is indeed wrong.
Do you happen to know what the correct formula is....

Yes, all hypnotists in Einstein criminal cult know the correct
formula. You can also infer it by combining two correct equations:

(1) frequency = (speed of light)/(wavelength)

(2) f' = f * (1 + phi / c^2) (Pound-Rebka; f is frequency)

Have you combined them? If you have, then:

c' = ?
