← ScienceWhich outcome regarding light propagates from spacetime curvature by a black hole?
A)Gravitational lensing increases light intensity✓
B)No lensing; full light signal loss
C)Blueshift increases light’s detected frequency
D)Reduced observed wavelength approaches zero
💡 Explanation
Gravitational lensing bends light because of the spacetime curvature generated by high-mass objects; therefore, the image is distorted and intensity increases rather than preventing light, because the path is curved through space-time.
