Which image distortion results when coherent light reflects imperfections?

💡 Explanation

A speckle pattern occurs because surface roughness causes constructive and destructive interference; this is speckle pattern degradation, distorting the image, therefore it becomes mottled, rather than exhibiting chromatic or spherical aberrations which arise from lens properties.
