Which artifact typically occurs when partially coherent light illuminates distant objects?

💡 Explanation

Speckle occurs because partial coherence causes interference adding constructively and destructively. Therefore speckle patterns appear depending on propagation rather than blurring from aberrations such as coma given focusing errors.
