SUMMARY
The equation governing the bending of light by a mass M is derived from the principles of general relativity, specifically in the context of gravitational lensing. When a light beam approaches a mass at a radius R, the trajectory is altered due to the curvature of spacetime around the mass. This phenomenon is quantitatively described in the referenced lecture notes from the University of Maryland, which detail the mathematical framework and implications of gravitational lensing.
