Which outcome occurs when an 18th-century maritime sextant's mirrors become desilvered under humid weather conditions?

💡 Explanation

Celestial observations become imprecise because mirror desilvering reduces light reflection via the Frunhofer diffraction mechanism, therefore, a dimmer image is projected, rather than leading to ambiguous computations using a properly functioning instrument.
