← HistoryWhich consequence results when early sextant mirrors experienced tarnish?
A)Reduced accuracy in angle measurement✓
B)Increased thermal expansion risk occurs
C)Accelerated wear of the worm gear
D)Distorted horizon line visibility forms
💡 Explanation
Reduced accuracy occurs due to decreased light reflection, because surface corrosion diminishes the mirror's **reflectivity**. This impacts navigation precision; therefore angle errors proliferate, rather than heat issues accelerating wear or optical line warping appearing.
