Which optical outcome occurred when medieval Islamic scholars polished lenses with progressively finer abrasives?

💡 Explanation

When polishing lenses with progressively finer abrasives, decreased surface roughness occurs because smaller particles remove microscopic imperfections, leading to a smoother surface. Therefore, reduced surface scattering results rather than aberration, precision or magnification which depend on lens geometry and refractive index control.
