← ScienceWhich deviation arises when starlight passes near a black hole?
A)Gravitational lensing magnifies distant galaxies✓
B)Blueshift reduces apparent stellar temperature
C)Relativistic aberration affects sky position
D)Doppler broadening changes spectral lines
💡 Explanation
Gravitational lensing results because spacetime curvature is created by the black hole's mass, making light follow geodesic paths altered via mass-energy equivalence; therefore causing lensing rather than other wavelength shifts, because those require relative motion.
