Which optical outcome improved celestial navigation due to Ibn Sahl's lens research in 10th century Baghdad?

💡 Explanation

When Ibn Sahl documented the law of refraction, understanding specific lens geometries could be engineered because the behavior of light passing through different materials became predictable, minimizing spherical aberration is possible when designing lenses. Therefore minimized spherical aberration resulted, rather than reduced chromatic aberration, which requires knowledge of dispersion, or enhanced magnification requiring advanced fabrication techniques.

• Which optical consequence arises when grinding a spherical lens during medieval times resulted in aspherical aberration?
• Which consequence results when tension decreases on the torsion springs powering a Roman ballista?
• Which environmental risk challenged Roman aqueduct design when traversing areas with limestone bedrock?
• Which destructive action increased when Roman onagers launched projectiles at castle walls at close range?
• Which structural compromise arose when incrementally increasing ziggurat height beyond clay tensile limit?
• Which navigational outcome was critically improved by the invention of the marine chronometer?
