← HistoryWhich function did the 'Equation of Time' correct for in pre-1800 mechanical astronomical clocks?
A)Irregularity solar orbit's apparent progress✓
B)Atmospheric refraction's impact angular position
C)Lunar parallax daily measurements deviation
D)Precession axial tilt slow cyclic changes
💡 Explanation
The Equation of Time corrected for the non-uniform apparent motion of the Sun due to Earth's eccentric orbit and axial tilt, causing variations in the length of solar days. Therefore, it fixed irregularities in the solar orbit, rather than refraction, parallax, or precession, which introduced different forms of astronomical errors.
