← ScienceWhich consequence results when optical coatings degrade unevenly?
A)Reduced destructive interference at interfaces✓
B)Increased total internal reflection
C)Enhanced thin-film transmission stability
D)Increased phase shift at Brewster's angle
💡 Explanation
Uneven degradation causes varied film thicknesses, reducing wavelength cancellation because it disrupts destructive interference; therefore, reflection from these coatings increases. Enhanced transmission requires uniform coatings, rather than irregular.
