← ScienceWhich phenomenon contributes to gravitational lensing around a black hole?
A)Spacetime curvature redirection of photons✓
B)Hawking radiation causes refraction
C)Event horizon absorbs all frequencies
D)Quantum entanglement influencing observation
💡 Explanation
Gravitational lensing occurs around black holes because spacetime curvature bends the path of photons. This redirection causes the light to curve around the massive object; therefore, it creates distorted images rather than absorption or other quantum phenomena.
