Problem

A set of object–image distance measurements for a concave mirror are plotted as

1/s_i

versus

1/s_o

. A linear fit gives a vertical-axis intercept of

(0.060 \pm 0.003)\,\text{cm}^{-1}

. Using these data, determine the mirror’s radius of curvature with its propagated uncertainty. (a)

(16.7 \pm 0.8)\,\text{cm}

(b)

(33.3 \pm 1.6)\,\text{cm}

(c)

(66.7 \pm 3.2)\,\text{cm}

(d)

(33.3 \pm 0.8)\,\text{cm}
