A short linear object of length L lies on the axis of a spherical mirror of focal length ƒ at a distance u from the mirror. Its image has an axial length L' equal to :
\[L\left[ \frac{f}{u-f} \right]^{2}\]
\[L\left[ \frac{u+f}{f} \right]^{1/2}\]
\[L\left[ \frac{u-f}{f} \right]^{2}\]
\[L\left[ \frac{2f}{u+f} \right]^{2}\]
