Which outcome reduces fringe contrast when partially coherent light illuminates mismatched optical flats?

💡 Explanation

Reduced fringe contrast results from source coherence because multiple interfering wavefronts reduce amplitude contrast during **superposition**, therefore causing increased background, rather than sharper lines. Other effects describe color distortions under varying parameters.
