Which consequence results when coherence degrades in optical interferometry?

💡 Explanation

Loss of coherence causes a decrease in fringe contrast because wave interference diminishes; therefore fringe visibility reduces, rather than noise decreasing, wavelength precision improving, with reduced coherence; the mechanism is the destructive interference.
