Problem: What is the focal length of the eye-lens system when viewing an object 32 cm from the eye? Assume that the lens-retina distance is 2.0 cm. Follow the sign conventions.

FREE Expert Solution

Lens equation:

$\overline{)\frac{\mathbf{1}}{{\mathbit{s}}_{\mathbit{o}}}{\mathbf{+}}\frac{\mathbf{1}}{{\mathbit{s}}_{\mathbit{i}}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbit{f}}}$

so = 32 cm
