Lens equation:
$\overline{)\frac{\mathbf{1}}{{\mathbit{s}}_{\mathbit{o}}}{\mathbf{+}}\frac{\mathbf{1}}{{\mathbit{s}}_{\mathbit{i}}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbit{f}}}$,
where so is the object distance, si the image distance, and f  is the focal length.

f = 25.0 cm

(a)

The object distance, so = 26.0 cm
