Which mechanism distorts atomic spectral lines observed near black holes?

💡 Explanation

Gravitational redshift shifts frequencies because spacetime distortion near the event horizon causes the observed electromagnetic wavelengths to increase. Therefore, the lines appear 'redder' instead of other effects, rather than wavelength compression, uncertainty blurring, or extraneous radiation solely responsible.
