← ScienceWhich destructive outcome can arise when coatings introduce phase changes?
A)Reduced optical transmittance at interfaces✓
B)Increased refractive index uniformity
C)Enhanced material thermal stability limit
D)Improved laser-induced damage thresholds
💡 Explanation
Reduced transmittance occurs because destructive interference cancels reflected light that undergoes thin-film interference, therefore the outcome is lower transmittance rather than enhanced stability; materials’ interfaces alter phase.
