Which outcome results when the *spatial coherence* of the laser source illuminating single aperture suffers degradation?

💡 Explanation

Increased speckle grain size will result because a spatially *incoherent* source generates many independent interference patterns rather than one uniform pattern; therefore, speckle size increases rather than creating a diffraction-limited spot due to coherence.
