Which outcome occurs when spatially incoherent light illuminates objects?

💡 Explanation

Decreased spatial coherence leads to overlapping interference patterns that reduce fringe contrast due to mutual interference from different points. Therefore, image quality degrades rather than improves because constructive interference isn't sustained across the whole field.
