← ScienceWhich effect occurs on photon energy traversing intense spacetime curvature?
A)Gravitational blueshift✓
B)Decreased Compton scattering
C)Reduced pair production threshold
D)Enhanced quantum tunneling probability
💡 Explanation
Gravitational blueshift occurs because photons gain energy when moving into a gravitational field governed by Einstein’s general relativity causing spacetime curvature. Therefore, their frequency increases; rather than alternatives which apply under different quantum conditions.
