A light source on top of a tower of height h emits light with
frequency f and speed c (relative to the source). The light reaches an
observer on the ground with frequency f' and speed c' (relative to the
observer).

Equivalently, a light source at the front end of an accelerating
rocket of length h and accelaration g emits light with frequency f and
speed c (relative to the source). The light reaches an observer at the
back end with frequency f' and speed c' (relative to the observer).

Consider equation (13.2) on p. 3 in:

http://student.fizika.org/~jsisko/Kn...Morin/CH13.PDF
f' = f(1+v/c) = f(1+gh/c^2) (13.2)

where v is the relative speed of the light source (at the moment of
emission) and the observer (at the moment of reception) in the rocket
scenario. By combining this equation with:

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

we obtain THE FUNDAMENTAL EQUATIONS OF NEWTON'S EMISSION THEORY OF
LIGHT:

c' = c+v = c(1+gh/c^2)

which CONTRADICT EINSTEIN'S 1905 FALSE CONSTANT-SPEED-OF-LIGHT
POSTULATE.

Einstein explicitly used the equation c'=c(1+gh/c^2) in the period
1907-1915, then replaced it with c'=c(1+2gh/c^2).
