← ScienceWhich outcome occurs when photon trajectories change in a gravitational field?
A)Spacetime curvature causes gravitational lensing✓
B)Gravitational redshift reduces photon energy
C)Time dilation affects photon frequency
D)Hawking radiation escapes black holes
💡 Explanation
Spacetime curvature near massive objects bends light paths, causing gravitational lensing because gravity affects spacetime itself; therefore different images form from warped photon paths, rather than simple energy losses or black-hole radiation which need event horizons.
