Which outcome reduces interferometer precision when path lengths exceed coherence?

💡 Explanation

Fringe visibility falls because constructive and destructive interference averages as path length differences exceed the source's coherence length, blurring fringes therefore precision degrades. This occurs rather than non-linear effects which require high intensity.
