← ScienceWhich optical effect increases near black hole event horizon?
A)Gravitational lensing magnification effect✓
B)Cherenkov radiation emission
C)Doppler shift attenuation
D)Refractive index homogenization
💡 Explanation
Gravitational lensing magnification increases near a black hole due to spacetime curvature. Because gravity causes light to bend, the magnification effect is amplified. Therefore, the image appears distorted, rather than attenuated by doppler shift because it's a light path distortion.
