That will not give the correct numbers, because in the scenario the test particle do fall radially, but the light beam does not, and is...

The point is: none. I just set up an scenario, derive the required Geodesic equations using the Schwarzschild metric, stating at the...

Don't know what this "vertical coordinate" is ¿?. I'm working with the Schwarzschild coordinates. The light pulse, moving from side to...

Note that the equations of motion for this case can be found in textbooks. Carroll's lecture notes equations 7.43, 7.44, 7.47 and 7.48...

Sure enough... For the test particle, the initial guess for the findroot() function is just the Newtonian approximation...

I attach an extremely exaggerated figure, to better understand the scenario. The laser is fixed at point A, at the left side of the...

As personal curiosity, I want to calculate which is the difference in "travelled height" between a photon that goes across the width of...

No. In the heuristic model you are trying to use, the original wave is partially absorbed by the material and re-radiated as the "wave...

I agree with that. There's an extended misconception about the change in speed being somehow due to the continually absorption and...
