Which effect on observed spectra results from the extreme spacetime curvature near a black hole?

💡 Explanation

Gravitational redshift occurs because photons lose energy escaping the intense gravitational field near the black hole, stretching their wavelength; therefore, the observed spectra shifts towards the red end, rather than to blue or line broadening, and is not relative to Lyman alpha.
