← ScienceWhich outcome occurs when high refractive index dielectric coatings induce phase shifts?
A)Enhanced destructive thin film interference✓
B)Reduced specular reflectance intensity
C)Increased radiative heat transfer
D)Suppressed broadband optical absorption
💡 Explanation
The coatings cause Fresnel reflection and constructive or destructive interference; the *enhanced destructive interference* reduces overall reflection, and shifts destructive peaks, because multiple reflections undergo phase shifts rather than direct reflection; therefore less light is reflected.
