On the influence of gravity on the propagation of light, with some comments on the A. Einstein`s 1911 Paper (1911-2022), Light Interaction With Gravity (The Mistake Made In 1911)

This is a review with some comments on the A. Einstein`s 1911 paper, which he published as one of his many attempts of the general theory of relativity. The main point of the idea is to propose a new approach about light and its motion as well as study the assumption made by A. Einstein concerning the possibility of the variation of the speed of light in presence of gravitational field.
