A set of object–image distance measurements for a concave mirror are plotted as 1/si versus 1/so. A linear fit gives a vertical-axis intercept of (0.060±0.003)cm−1. Using these data, determine the mirror’s radius of curvature with its propagated uncertainty.
a) (16.7±0.8)cm
b) (33.3±1.6)cm
c) (66.7±3.2)cm
d) (33.3±0.8)cm
