← ScienceWhich outcome occurs when partially coherent light illuminates rough surface?
A)Speckle pattern formation is reduced✓
B)Perfect destructive interference dominates
C)Maximum chromatic aberration emerges
D)Rayleigh scattering becomes insignificant
💡 Explanation
Reduced speckle occurs because the decreased temporal coherence limits constructive interference. Partially coherent sources don't produce persistent speckle patterns; therefore, the grainy effect diminishes, rather than other interference or scattering phenomena that hinge on differing requirements.
