Which consequence results when a medieval water clock's viewing hole is too small?

💡 Explanation

Reduced hole diameter limits the observer's perception because the resolving power (Abbe diffraction limit) decreases as the aperture constricts, thereby reducing light throughput; therefore, shadow movement becomes difficult to discern, rather than impacting refractive calculations.
