← HistoryDuring 18th-century celestial navigation, which outcome occurred because thermal expansion affects metal sextant components?
A)Reduced sighting accuracy possible✓
B)Lighter frame aided portability
C)Enhanced mirror coating longevity
D)Easier scale engraving processes
💡 Explanation
Thermal expansion impacts sextant frame dimensions due to changing temperatures; this dimensional change directly affects alignment and the angle measurement via parallax, therefore reducing precision of celestial fixes rather than aiding any specific feature improvement.
