A physics student graphs

1/s_i

(vertical axis) versus

1/s_o

(horizontal axis) using data from a concave spherical mirror. The graph is a straight line that crosses the vertical axis at

0.040\,\text{cm}^{-1}

. Which quantity is represented by this vertical intercept? (a)

\displaystyle -\frac{1}{f}

(b)

\displaystyle \frac{1}{s_o}

(c)

\displaystyle \frac{1}{f}

(d)

\displaystyle \frac{1}{R}
