Which outcome occurs when a wide light source illuminates a double-slit?

💡 Explanation

With a wide source each point creates its own interference pattern, but off-axis sources shift fringe positions; therefore, incoherence causes fringe blurring via superposition, rather than creating sharper or only diffraction, because source coherence is critical.
