Which outcome occurs when an 18th-century ship’s sextant mirror has corrosion-induced tarnishing?

💡 Explanation

Corrosion on a sextant decreases image clarity due to reduced light reflection via specular reflection, distorting the perceived angle of celestial bodies, because the observer cannot precisely align the body with the horizon; therefore, angle measurements become inaccurate rather than influencing timekeeping or structural integrity.
