← ScienceWhich consequence results when an aperture limits coherence?
A)Increased far-field diffraction widening✓
B)Symmetrical chromatic aberration increase
C)Reduced average output intensity
D)Compensated spherical waveform reduction
💡 Explanation
A smaller aperture increases diffraction because the Huygens-Fresnel principle predicts wider spread from smaller sources; therefore, diffraction widening increases, rather than intensity loss or aberration compensation, specifically due to the limited spatially coherent wavefronts.
