← HistoryWhich outcome occurs when ablating surfaces of a sundial gnomon?
A)Inaccurate determination of midday✓
B)Consistent material fatigue reduction
C)Greater structural weight distribution
D)Improved surface reflectivity indoors
💡 Explanation
Ablation changes the location of the shadow, leading to inaccurate timekeeping via shadow-casting, because the **index error** changes. Therefore indication of midday shifts, rather than any change to material properties; alternative answers do not involve shadow angles.
