I have discussed in an earlier paper, “The Gravitational Deflection of Light Beam in the Reciprocal System,” the effect of gravitation on the bending of the locus of a photon. Even though the role played by the coordinate time associated with the gravitational motion in deflecting the path of light was correctly depicted therein, I believe that the mathematical implications were not correctly brought out. Especially, in the case of equation (6) there, though its existence was correctly recognized, its physical significance was misconstrued. The present paper, therefore, attempts to overcome these shortcomings and derives the mathematical expression for the angle through which the path of light beam deflects in the vicinity of a mass.
