← HistoryWhat outcome follows when Medieval lenses exceed design limits?
A)Spherical aberration reduces image sharpness✓
B)Chromatic aberration enhances color separation
C)Diffraction fringes improve fringe visibility
D)Mirage effects stabilize atmosphere locally
💡 Explanation
Lenses exceeding design parameters cause **spherical aberration** because light rays focus at different points, depending on their incidence. Therefore, blur occurs rather than the alternatives of enhanced colors or crisper imaging, assuming idealized conditions.
