Lens equation:

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

1. A 1.0-cm tall object is 10 cm in front of a converging lens that has a 30 cm focal length.

a) Use ray tracing to find the position and height of the image. To do this accurately, use a ruler or paper with a grid. Determine the image distance and image height by making measurements on your diagram.

b) Calculate the image position and height using the thin lens and magnification equations. Compare with your ray-tracing answers in a).
