fringe visibility

Fringe visibility is a measure of how clearly you can see the bright and dark patterns, called interference fringes, created when waves like light overlap. When waves are very coherent and in sync, the fringes are sharp and bright, meaning high visibility. If the waves are less coherent or disturbed, the fringes become faint or blurry, indicating low visibility. Essentially, fringe visibility quantifies the contrast of these interference patterns, helping scientists assess the quality of wave coherence and the degree of interference in experiments involving light or other waves.
