Which consequence results when gravitational lensing occurs around a black hole?

💡 Explanation

Gravitational lensing increases observation redshift of background objects because the equivalence principle suggests gravity behaves like *acceleration*, therefore increasing light's wavelength shifts to red, rather than light conserving energy at original wavelengths.
