← ScienceWhich consequence results when a photon passes near a black hole?
A)The photon red-shifts significantly.✓
B)The photon's speed increases.
C)The photon's wavelength decreases.
D)The photon splits into particles.
💡 Explanation
A photon red-shifts because the extreme gravity near a black hole causes spacetime curvature, enacting gravitational redshifting. Therefore, the photon loses energy and increases wavelength rather than gaining energy or changing speed because of being near to a black hole.
