Which consequence arises when spatially coherent laser light illuminates a rough metal surface?

💡 Explanation

A speckle pattern forms because the surface irregularities cause constructive and destructive interference of the coherent light. Therefore, a speckled appearance is observed, rather than uniform reflection, because path lengths differ slightly causing complex spatial interferences.
