Which outcome occurs when a photon's path bends near a black hole?

💡 Explanation

Gravitational redshift increases because spacetime curvature causes photons to lose energy climbing out of a gravitational well; this is due to the principle of equivalence. Therefore, the photon shifts to lower frequencies, rather than gaining energy or generating particles.
