← ScienceWhich outcome often results when thin-film coated optics degrade?
A)Increased light scattering at specific wavelengths✓
B)Uniform decrease across relevant spectrum
C)Reduced thermal sensitivity shifts interference minima
D)Material ablation threshold becomes stable over time
💡 Explanation
Increased light scattering occurs because surface defects initiate **thin-film interference**, leading to the destructive interference of reflected coherent light at certain wavelengths, therefore creating color shifts rather than stability because material properties dominate.
