Which 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.
