Which mechanism disrupts fringe visibility if two quasars' light beams with distinct path lengths converge on Earth using Very-long-baseline interferometry?

💡 Explanation

Temporal coherence defines the correlation between a wave and itself delayed in time; without it interferometry degrades because the phase relationship becomes undefined. Therefore, loss of temporal coherence reduces fringe contrast, rather than scattering, lensing, or chromatic effects playing primary roles.
