Which observed effect results when light transits a gravity lens?

💡 Explanation

Apparent object brightness occurs in gravity lenses because gravitational curvature follows photon paths creating lensing. Gravitational lensing enhances brightness therefore observed magnitude increases, rather than frequency shifts related to relative velocity.
