← HistoryWhich outcome occurs after a sextant's mirrors lose perpendicularity?
A)Bearing errors become angle-dependent✓
B)Latitude readings drift systematically
C)Celestial body images vanish entirely
D)Chronometer drift increases drastically
💡 Explanation
Sextant error arises from Loss of Perpendicularity because non-perpendicular mirrors induce angular displacement according to the Angle of Incidence principle; therefore angular measurement varies because incident angle inaccuracies are increased, rather than systematic shifts or lost visibility.
