Which effect is observed when light traverses spacetime curvature near a black hole?

💡 Explanation

Gravitational blueshift occurs because photons gain energy approaching higher gravitational potential near black holes, resulting from spacetime curvature. This follows energy conservation; therefore, photons increase in frequency, rather than undergo time dilation as they fall inward.
