← ScienceWhich risk increases when imperfect lens coatings induce reflections?
A)Reduced signal-to-noise ratio occurs✓
B)Total internal reflection reverses
C)Increased chromatic aberration develops
D)Increased numerical aperture appears
💡 Explanation
Signal-to-noise decreases because spurious wavefronts experience constructive and destructive interference, forming noise patterns. Therefore, lower fidelity results, rather than internal reflection changes/optical element effects which arise from different index variations/mechanisms.
