Which consequence results when optical path differences increase?

💡 Explanation

Increased optical path differences lead to increased phase shifts among interfering waves; therefore, **constructive and destructive interference** regions blur, reducing fringe contrast, because fringes require phase coherence, rather than distinct spectral effects or diffraction phenomena.
